CPFs: support for objref in DTD

Are 'objref' types supported in the current rtt (1.10)? It's in the CPF DTD...

Basically, I am in need to create a specific type (not standard short, long, double, etc..) where I could perform introspection and bind with a class. I can do it through multiple simple elements and write binding logic, but I was trying to avoid repetition (in the XML) or as well advantage of XML element references.

On that note, is binding such as that used by JAXB, C# XML data binding, or CodeSynthesis C++/XSD on the roadmap to be supported by RTT?
