New Revision: 516168

URL: http://svn.apache.org/viewvc?view=rev&rev=516168
Log:
Added RenderContentTransform which does both content and subcontent rendering.
Linked to it in FreeMarkerWorker, but did not remove other transform defs.
This has not been tested - will be doing that now - just making available to other hackathoners.

Added:
