Summary: Duplicate global variable declaration exception

Initial Comment:
Although xsddoc works fine from the command line with my schema 
(included below), in Ant, i get a Duplicate global variable declaration 
exception.  Stack trace is at the bottom of this message.  I have not 
modified any of the jar files in the ant/lib directory.

I am using:

xsddoc-0.4-beta
apache-ant-1.6.1

xalan (within xsddoc lib directory) xalan-j_2_3_1_01

xalan (in ant lib directory) 
ant-xalan1.jar, ant-xalan2.jar (given the size of these files, I think these 
are only running another xalan somewhere else but i don't know 
enough about the implementation of Ant to answer that any better)

Here is the schema I was running -- xsddoc runs it fine from the 
command line but fails to run in Ant

Replacing ant's existing xalan.jar with Version 2.6 worked, and everything is 
fine.

Thanks for the quick fix!!!!

Fixed in CVS.
Will be available with next release 0.5 beta

Thanx for the extensive information.
I was able to reproduce it with some old versions of xalan.
And indeed we have a duplicate variable declaration in 
component.xsl and the included xmldoc.xsl (mainSchema).
I'm not sure if this is invalid with respect to the XSL-T 
specification, but anyway it' easy to solve and will be fixed in 
the next release 0.5 beta.

For now you could update your ant installation to a newer 
version of XalanJ by dropping the corresponding file Xalan.jar 
into the lib folder of your ant installation.
XalanJ Version 2.5.1 or higher should work
