Subject: libxml2 does xmlSchemaValidateDoc() support xml schema extensions?

Hi

I am using libxml2. I use xmlSchemaValidateDoc() to make sure my xml is valid. Recently we started using Extension to define new complexTypes.

The description for extensions can be found at http://www.w3.org/TR/xmlschema-0/#DerivExt  

These instance do not validate using libxml2. I am able to validate these instance using java version "1.6.0_29"

Attached is my test Zoo.xsd, and the instance I am trying to validate
