JSF: urls, xhtml syntax and tc~ui~faces~extended~renderkit

I have NW 7.5sp1 with NWDI installed.

There is no updated manual for SAP JSF 2.2 so I am asking:

1. Where is actual list of URI/namespaces for JSF under SAP NW?

http://java.sap.com/jsf/core

http://java.sun.com/jsf/core

http://java.jcp.com/jsf/core

or

http://xmlns.jcp.com/jsf/core ?

2. How to use XML syntax for jsf (not ugly JSP one)?

3. What is the way to compile jsf with tc~ui~faces~extended~renderkit ?

Thank you in advance.
