Schema valication bug?

["Blankenship, David" <Da...@kla-tencor.com>]

Xereces-j: 1.1.2
Jdk: Sun 1.3
OS: NT 4.0

I think this is a bug in Xerces, but I am willing to be convinced otherwise.

I have run into a validation problem while trying to build a recursive
structure. I have created a small test case that demonstrates the problem
that I am having. I am using xsd:choice to get around the lack of support
for xsi:type. I am able to validate using XML Spy, but I get the following
errors while validating with Xerces-j:

[error] file:///d:/source/xml/Tree.xml 6:10 Element type "fork" must be
declared.
[error] file:///d:/source/xml/Tree.xml 11:10 Element type "fork" must be
declared.
[error] file:///d:/source/xml/Tree.xml 16:13 The content of element type
"branch" must match "(fork)+".


Thanks,

There are a couple of bugs in Xerces1.1.2 that causing the problem you saw.
I already fixed them and the latest source in CVS works fine with your
example.

Also, the support for "xsi:type" has also been added to the latest source.

I expect another release coming out real soon.
