Yes I understand that.

CPS won't see the schemas directly, only through the JCR. Well maybe  
for prototyping we can load them from XSD but that's temporary.

JackRabbit can already convert XSD to its internal node type  
definitions  
(org.apache.jackrabbit.core.nodetype.converter.SchemaConverter).

Yes that's what I was saying above (introspection of the node types  
in the JCR at startup).

Sure.
