[xsd-users] Error with X3D schema

[Hasan, Eric]

I'm getting the following error when generating c++ code for the X3D
schema. 

$ xsd cxx-tree x3d-3.0.xsd

I downloaded the individual X3D schema files from web3d.org (not the
zip file which, is old) and removed the includes that were causing a
problem for this guy:

platform: Linux x86
distro: fedora core 4
compiler: gcc 3.2.3 20030502 
codesynthesis version: v2.3.1 BETA
xerces-c version: 2.7.0-3

Any help would be appreciated.
