It is very strange to hear such question from Sergey Smirnov...
These schemas are used in generating styles (.xcss):
These schemas are used in component templates in CDK (.jspx):
So, RichFaces use them all. And developers those write custom components and styles need them.
Unfortunately we do not have schemas or DTDs for mentioned URLs :( . We're working on CDK guide where you can find information about tags and their values. As for now it can be found here: http://repository.jboss.org/maven2/org/richfaces/docs/cdkguide/en/3.2.2.CR3/
Those starting from http://ajax4jsf.org/ aren't treated as schemas really. Only the prefix (vcp, ajax, etc.) is matched. Here is the place where they all are registered: http://fisheye.jboss.org/browse/RichFaces/trunk/cdk/generator/src/main/java/org/ajax4jsf/templatecompiler/elements/A4JRendererElementsFactory.java?r=2569 .
Some information for: http:/jsf.exadel.com/template
http:/jsf.exadel.com/template/util can be extracted from this: http://fisheye.jboss.org/browse/RichFaces/trunk/framework/impl/src/main/java/org/ajax4jsf/renderkit/compiler/HtmlCompiler.java?r=7096 and related classes.
We're going to prepare schemas for these namespaces and use some JAXB-like runtime instead of digester but this work has not been started yet.
P.S. I'll try to find time this week and prepare schema files.
Do you have any news about the schema availability (namespaces http:/jsf.exadel.com/template, http:/jsf.exadel.com/template/util).
I'm using RF 3.3.2.SR1, but I don't find them.
Am I missing something ?
