• Link parsers + -link rendering (XWikiSyntaxRenderer)-
• Caches
  • Add suppor for caching macro block generation
  • Add caching of "static" blocks
• More syntax support
• -Finish implementing the xhtml, velocity macros (parameters support)-
• Implement all missing macros (all the radeox macros we had)
• Modify document link saving (no need for rendering, just parsing)
• -Make preview work-
• Find a way to move all old rendering code to a separate package so that it can be easily removed later and so that we have some clean code left (if possible)
• Make the XHTML parser fully work (lots of issues, see http://code.google.com/p/wikimodel/issues/)
• -Make Inline mode work-
• -Modify the Document Information panel in edit mode so that it lists all doc that are included with the new rendering {include} macro.-
• Question: how do we support automatic inline editing?
• Decide on syntax elements
  • -escaping blocks of text- ({ { { } } } - need to be implemented in wikimodel)
  • -double curly braces for macros?- (yes)
  • images in links?
  • -Tables in wiki syntax?- (no, only macro)
  • quotation character and quotation blocks
• Check for view rights in the include macro
• Groovy refactoring and new grooy module/components
• Add translation support in include macro
• -Add api to convert parameters in values (boolean, integers etc.)-
• -Modify macro api to be able to know where the processed macro is located in the XDOM-
• -Add id Block (and it's corresponding macro that add the block in the dom) which generate anchor in HTML for example to be used has target in the links-
• TOC macro:
  • -generate list tree from sections-
  • -support "numbered" parameter-
  • -support "scope" parameter-
  • add internal link targeting sections (temporary solution already committed waiting for LinkBlock to support children blocks as label)

... and a lot more I'm sure (this list should be edited as we progress)
