[castor-user] Using castors schema model and specialization patterns

[Oliver Fourman]

Hello list,

I started using castor's schema model to generate own schema 
definitions. Now I want to apply a specialization pattern to my 
definitions by using following schema elements: "restriction base", 
"complexContent" and the anonymous "simpleType". Today all my attempts 
were in vain.

I found some articles, that match my intention:
http://www.w3schools.com/schema/el_restriction.asp 
http://www.mail-archive.com/dev@castor.codehaus.org/msg00455.html
http://jira.codehaus.org/browse/CASTOR-1238

So it is possible at all to build such a schema with Castor's XML Schema 
API?
Here my example: http://pastebin.com/891664 (highlighting)

Best regards,
Oliver
