Description

While we have some form of extensibility already in the query parser there are ways to improve this:
1) Provide base lexer (abstract), strict lexer (CMIS) and extended lexer as an example
2) separate walker base (abstract) from strict walker
3) adapt query support classes so they can be used with extended classes.

Note: Keep old support class for compatibility
