As far as I can tell you can't determine what you want using the
Xerces XSModel API, but I don't think it is designed to parse an XML
Schema in such detail. It implements the abstract model defined in
the XML Schema Structures specification and is primarily intended
for use of validation, i.e. it is read-only and light-weight. I
think you need another API like the Eclipse XSD model [1] to analyze
(and possibly modify) the source XML Schema document(s) in greater
detail.

Right, there's no representation of a reference to an attribute group
definition in the model. The {attribute uses} contained in them get
absorbed into the complex type definition's {attribute uses}. The spec
describes how that's computed here:
http://www.w3.org/TR/2004/REC-xmlschema-1-20041028/#declare-type. See
the definition of {attribute uses) in the sections titled "Complex Type
Definition ... Schema Component".

Thank you Stanimir,
I will check out the API that you recommended.
