I would like to see the spec provide more explicit documentation of exactly which new features are not
available in JSP. I sent the following two proposals to the EG list:
1. Let's update the spec to state specifically what functionality (down to the tag/tag library level) is not
supported in JSP.
It is possible that this information is already present, but if not, I would like to see a section that
contains a list of all of the new tags that were added in JSF 2 that are specific to Facelets (ie. not
available in JSP).
2. Let's update the Facelets PDL docs to identify tags that are not present in JSP.
For example, the PDL doc for f:ajax should state that it is not available in JSP.
Regarding #1... I think it is important to have this information available in a centralized location, where
it can be easily found/understood by JSP users. #2 should also help to avoid confusion.
