[jsr-314-open] Spec clarification: features not available in JSP

[Andy Schwartz]

FWIW, I logged the following spec issue to track this:

Issue 636: Clarification of Facelets-only (non-JSP) functionality [1]

While I was at it, I also logged this spec issue:

Issue 635: Obsolete references to UIInput.encodeEnd() for default 
validator wiring [2]

To track this concern raised by Leonardo on the MyFaces thread:

> In jsf 2.0 spec section 3.5.3 Validation Registration says this:
>
> *"....The default validators are appended after any locally defined
> validators once the EditableValueHolder is populated and added to the
> component tree. See the javadocs for UIInput.encodeEnd() for the normative
> specification. A default validator must not be added to a UIInput if a
> validator having the same id is already present....."*
>
> First note that UIInput.encodeEnd() method does not exists!
