Allow running LIKE queries on XWQL relational stored list member values

The following query seems to produce one line for each value of the "item.parameters" relationally stored list property:

{{velocity}}
#set ($results = $services.query.xwql("SELECT doc.fullName, object.someListProperty FROM Document as doc, doc.object(Some.Class) AS object").execute())
|=|=
#foreach ($result in $results)
  #foreach ($subResult in $result)|$subResult#end

#end
{{/velocity}}

Also, we are able to query for exact matches on list item values:

...WHERE 'somevalue' MEMBER OF object.someListProperty...

However, we are not able to perform `LIKE` (pattern) matches on list item values. None of the following work:

• SELECT doc.fullName, object.someListProperty FROM Document as doc, doc.object(Some.Class) AS object WHERE object.someListProperty LIKE 'abc%'

• SELECT doc.fullName, listItem FROM Document as doc, doc.object(Some.Class) AS object, object.someListProperty as listItem WHERE listItem LIKE 'abc%'
