Upgrade to CSS4J 1.0.0 RC1 & JCLF 4.0.4

Version 0.43.2
--------------
 * Core:
- NSAC: add SAC_ELEMENT_REFERENCE to LexicalUni2.
- NSAC: LexicalUnit implementations must implement LexicalUnit2's getCssText().
  For identifiers and colors, the serialization should be close to how the value
  was specified.
- NSAC impl.: bug: the parser was rejecting legitimate escaped characters 
  [regression introduced in 0.42.4].
- NSAC impl.: more efficient handling of quoted strings and character escapes.
- NSAC impl.: implement SAC_ELEMENT_REFERENCE.
- NSAC impl.: be less permissive about accepting at-rules after an unexpected 
  character.
- NSAC impl.: not all the required whitespaces were being inserted into rules 
  processed through 'ignorableAtRule' (bug).
- NSAC impl.: if IEVALUES flag is set, try to identify escaped value hacks that
  have a valid CSS syntax, like in font-family declarations targeting IE.
- NSAC impl.: improve the parsing of @font-feature-values and @keyframes rules 
  when escaped identifiers or strings are used.
- NSAC impl.: for identifiers and hex colors, LexicalUnit.toString() attempts 
  to give a representation closer to what was parsed.
- TokenProducer: fix a bug when the last character was a possible word 
  character.
- TokenProducer: fix bug when the last character was part of the beginning of a 
  comment.
- TokenProducer: cleanup/optimization in a hot code path.
- DefaultEntityResolver: allow subclasses to override the opening of the 
  URLConnection to the DTD source. Create a TestEntityResolver.
- Add a second constructor to DefaultEntityResolver. Default constructor now 
  only allows connections to W3C.
- DefaultEntityResolver: load XHTML 1.1 modules and other DTDs from classpath.
- DefaultEntityResolver: if the resource is not known to the resolver and the 
  protocol is not http/https, or the whitelist is enabled and the host is not 
  whitelisted, throw an exception instead of silently returning null.
- DOM impl.: fix a toString() bug in DocumentTypeImpl when only a system ID is 
  present.
- DOM impl.: use safer XML parser defaults in XMLDocumentBuilder.
- DOM wrapper: avoid unnecessary argument in internal constructor.
- CSSOM: do not use CSSStringValue as the base class for identifiers and 
  attributes.
- CSSOM: use the new LexicalUnit2.getCssText() method to set identifier cssText
  if the parser is NSAC.
- CSSOM: add a shorthand serialization method to StyleFormattingContext.
- CSSOM: pass IE hacks in MediaQueryFactory, preserving the serialization.
- CSSOM: use the new escape() methods in ParseHelper.
- CSSOM: introduce new configuration flags for sheet factories, with three 
  possible behaviours for CSS string values: preserve -if it is efficient- the 
  quote character used (default), or use -if efficient- a specific character 
  (double or single quotes).
- CSSOM: add CSS_ELEMENT_REFERENCE to CSSPrimitiveValue2, and implement it.
- CSSOM: calc expressions inside functions were omitting the 'calc' name (bug).
- CSSOM: support setCssText() in custom property ('var()') and 'env()' values.
- CSSOM: support custom properties ('variables') in border-radius shorthands.
- CSSOM: do a sanity check for values before serializing the generic (outline, 
  etc) shorthands in computed styles.
- CSSOM: more accurate processing of color values in the shorthands serialized 
  for minified computed styles (avoid building broken shorthands from bad
  values).
- CSSOM: add IE hack detection logic to minified serialization of computed 
  values.
- CSSOM: add a couple of serialization methods to the default 
  StyleDeclarationErrorHandler.
- Assorted new tests and small test cleanup (like a couple of tests that weren't
  testing what was intended, broken DTDs or the inefficient use of a factory
  constructor).
- Changes to CSSOMBridge to enable testing from other modules (required for
  JPMS).
- Add automatic module name to Maven POM, and upgrade to latest Maven plugins.

 * Dom4j module:
- Prepare project for Java modularization.
- Add automatic module name to Maven POM.
- Adapt unit tests to string value behaviour changes in core.
- Reduce the visibility of implementation inner class
  XHTMLDocumentFactory.DOM4JCSSStyleSheetFactory to package.
- Entity tests: workaround for dom4j 2.1.1
- Maven POM: depend on Jaxen 1.2.0.

 * Agent module:
- Move the entire module to the new agent.net subpackage, to make it compatible 
  with Java modularization.
- Add automatic module name to Maven POM.

 * AWT module:
- Add automatic module name to Maven POM.

Version 0.43.3
--------------

  hasKeyword() and hasArgument() NSAC methods.
- NSAC impl.: fix a bug parsing escaped values in attribute selectors

  selectors.
- NSAC impl.: fix a bug setting flags in attribute selectors that are part of 
  combinator selectors.
- NSAC impl.: improve error detection in functional pseudo-classes like ':lang'.

- DOM impl.: introduce an ExtendedNodeList interface, featuring a 
  'contains(Node)' method.
- DOM impl.: unify ElementList and DOMElementList, removing the latter.
- DOM impl.: migrate to a faster implementation of node trees that does not 
  rely on Java collections.
- DOM impl.: add several iterators to ParentNode (available in elements etc.).
- DOM impl.: Add NodeIterator and TreeWalker creation to DOMDocument.
- DOM impl.: getElementsBy(Tag|Class)Name live collections were not always 
  updated when they should (bug).
- DOM impl.: DOMDocument: set the parent node for DocumentType in document's 
  constructor instead of XMLDocumentBuilder (bug).
- DOM impl.: Document.insertBefore was not properly checking for duplicate 
  document elements (bug).
- DOM impl.: Document.getFirstElementChild() and getLastElementChild() were 
  returning the document element's element child instead (bug).
- DOM impl.: Document.getChildren() was also giving the children of the 
  document element (bug).
- DOM impl.: fix bugs when adding and inserting a document fragment, or 
  replacing a node with it.
- DOM impl.: fix a bug cloning DocumentFragment nodes.
- DOM impl.: fix a bug cloning elements.
- DOM impl.: the substringData and replaceData methods of Text, character data 
  and comment nodes were not behaving as per the specification when the sum of 
  the 'offset' and 'count' arguments was larger than the data (bug).
- DOM impl.: correction to a few DOMExceptions that are thrown when creating 
  Elements and Processing Instructions with wrong names in DOMDocument.
- DOM impl.: getLastStyleSheetSet() was probably not returning the expected 
  values.
- DOM impl.: fix a potential XML injection in createProcessingInstruction.
- DOM impl.: xmlns attributes now always return the 
  http://www.w3.org/2000/xmlns/ namespace uri, but can be created with a null 
  namespace without throwing an exception.
- DOM impl.: implement NonDocumentTypeChildNode.
- DOM impl.: small internal refactor to querySelectorAll.
- DOM impl.: HTMLDocument: for consistency with the other setIdAttribute 
  methods, ignore attributes from non-HTML namespaces in setIdAttributeNode.
- DOM impl.: fix a bug where a Text node could not be added to a 
  DocumentFragment.
- DOM impl.: in isEqualNode(), normalize the nodes before comparing lengths, 
  not after (bug).
- DOM impl.: when a node has no defined value, setting it should have no effect.
- DOM impl.: not all the required characters were being expanded as entities 
  when serializing attributes (bug).
- DOM impl.: ID attributes now have an 'ID' typeName as returned by 
  getSchemaTypeInfo().
- DOM impl.: recognize 'xml' as a reserved namespace prefix.
- DOM impl.: reject attempts to insert unsafe values into CDATA-sections and 
  processing instructions.

- DOM impl.: XMLDocumentBuilder: do not enforce a no-DTD configuration when 
  there is no EntityResolver set. With the default configuration for the parser 
  factory, this means that parsing would fail instead of silently proceeding.
- DOM impl.: XMLDocumentBuilder: in the default constructor, set 
  'http://xml.org/sax/features/namespace-prefixes' and 
  'http://xml.org/sax/features/xmlns-uris' to true.
- DOM impl.: add setIgnoreElementContentWhitespace(boolean) to 
  XMLDocumentBuilder.

  factory flags.
- CSSOM: serialize attribute value selectors using single or double quotes 
  according to the flag specified to the factory.
- CSSOM: fix a bug when restoring a previous shorthand-specified value after 
  removing a property.
- CSSOM: fix bugs building a referrer to use with loadStyleSheet().
- Tests: remote test for DefaultEntityResolver was outdated.
- Tests: add Daniel Eden's animate.css and Sergey Pimenov's Metro UI CSS to the 
  contrib tests (noticeable increase in download size!).
- Tests: clean-up of 'throws' declarations.

 * Dom4j module:
- Element.setIdAttributeNode(): if an ID attribute which is not "id" (case 
  insensitive) is being set, fall back to default upstream behaviour (which 
  currently throws an exception).
- getLastStyleSheetSet() was probably not returning the expected values.
- More appropriate names for two private methods.
- Tests: clean-up 'throws' declarations.
- Tests: adapt to changes in core.


 * Agent module:
- DefaultUserAgent: ignore element content whitespace.

  need to manually call getSheet().
- DOM impl.: before setting the title of a style sheet from an attribute value, 
  trim() it.
