Major When working with the repository query API, it's not possible at this time (or very bothersome) to query a list of contents matching some criteria and limiting the query to a subtree of the sitemap (for example retrieve all the contents which are referenced by any page under a certain section).
It would be interesting to have the possibility to do that, for instance with a subclass of ContentQuery with a 'page' or 'path' parameter on the execute method.
[CMS-568] ContentQuery limited to a part of the sitemap

added a comment - Cedric proposed to create a new content query type called "ContentOnPageQuery" started implementing it, and I made some modifications.
The implementation seems to work here for me (without testing with composite metadata, though).
Here is a proposition of implementation. Most of it is from Cedric (with a bit of refactoring), based on the existing ContentQuery and ContentPage API/JCR implementation. The code certainly needs some review, as I'm not very familiar to JCR XPath-query syntax.

Commited all the ContentOnPageQuery API & implementation.
