JAXB Schema problems with complexTypes

Howdy all,

	I work with a company that is trying to use JAX-B generated code in a 
number of projects.  The most recent one involves a rather complex set 
of Schemas.  In these Schemas there are complexTypes defined using 
extension from other complexTypes.  Some of these complexTypes are 
based off of other complexTypes using restriction.  XmlSpy validates 
everything, as does a recent SAX parser.  However xjc spits out errors 
when I try to use JAX-B to generate code from the Schemas, and no code 
is generated.  The errors look like this:

[ERROR]  Base complex type is derived by restriction, while this 
complex type is derived by extension

	This problem occurs 5 or so times throughout the Schema.  We have a 
little bit of control over the Schema we are using ( though another 
company is mainly responsible for it ).  However we have no control 
over the base Schemas that this Schema uses in its namespace.
	I tried running with '-extension' and adding in the 
complexTypeSubstitution attributes, but still no luck.  Does anyone 
have any experience with this problem or any advice to offer?
