extension doesn't work right?

[Frank Zhou]

Hi, All,

I am trying to use Xerces XML Schema parser and found
that it seems the parser doesn't work with extension.
Specifically, in the following schema, element
ABConnect is defined to an extension of base type
GenericAccountType, but when I parsed the schema, I
found the element ABConnect doesn't contain any info
in the base type, and when I debug the Xerces code
(addElemDecl in TraverseSchema) I noticed that the
scopeDefined for the elements in the base type is -2
while the enclosing type is 1.

I am using Xerces 1.3.1.

Anyone can give me suggestions what might go wrong?

Thanks much in advance.

Frank
