Hello Volunteers,

In a move designed to demonstrate our commitment to community, and
showcase the independence of our technology from any one company, all
newly created XML namespaced artifacts in JSF 2.2 must use the new
xmlns.jcp.org namespace instead of java.sun.com. For example, the
faces-config.xml schema will be <http://xmlns.jcp.org/xml/ns/javaee>
instead of <http://java.sun.com/xml/ns/javaee>.

This change impacts two areas: 1. XML files. 2. Facelet Taglib URIs

SETION: 1. XML Files

Any XSD ending with _2_2.xsd will have the new namespace applied.

This diff exemplifies this sort of change.

The complete list of files impacted is:

web-facelettaglibrary_2_2.xsd
web-facesconfig_2_2.xsd
web-partialresponse_2_2.xsd

SECTION: 2. Facelet Taglib URIs

Consider the Facelet VDLdocs at [1]. The following libraries are new in
2.2, and will only have the new namespace.

Library URI
------- ---
Pass Through Attributes http://xmlns.jcp.org/jsf/passthrough
Pass Through Elements http://xmlns.jcp.org/jsf

The remaining libraries are pre-existing and will respond to both the
old and the new namespace.

Library OLD URI NEW URI
------- ------- -------
Composite Components http://java.sun.com/jsf/composite http://xmlns.jcp.org/jsf/composite
Faces Core http://java.sun.com/jsf/core http://xmlns.jcp.org/jsf/core

Please let me know if you have any comments about this.
