Question figuring out if a particle is from a base class

Hello,
  I am trying to use Xerces-J's XML schema API to parse and analyze a
schema. As I am iterating through the XSModel, I get the XSParticle from an
XSComplexTypeDefinition and iterate over its terms. I find that I am getting
the XSElementDeclaration objects for all elements defined in both in the
current complex type definition and the ones in its base types.

  How can I distinguish which elements are from the current complex type and
which ones are from the base types? Thanks.

Hello Nagaraj,

If you're looking at an extension, the particle returned from the
XSComplexTypeDefinition should contain a sequence XSModelGroup with its
first particle being the same as the XSParticle from the base type.

Thanks.
