[xsd-users] Problem in translating schema to C++ (following parser guide)

It is possible to use C++/Tree with large files (i.e., those that won't
fit into memory) with a bit of extra work. For larger schemas it may
still be easier than C++/Parser. For more information on this see the
'streaming' example in the examples/cxx/tree/ directory of the XSD
distribution (only available in XSD 3.3.0 or later).

This is Mono's xsd.exe utility. If you are using the XSD package
from the Debian/Ubuntu/Fedora/etc repository, then the compiler
name is xsdcxx.

Hm, that's odd. I assume hello.xsd is the unmodified schema from the
guide, right? I just tried the following on my Debian box:

1. Install xsdcxx 3.2.0.1-1.1+b3 from the Debian testing repository.
2. Copy and paste the schema from Section 2.1 of the online guide to hello.xsd
3. Run xsdcxx cxx-parser --xml-parser expat hello.xsd

And everything works without any problems.

Do you get the same error with xsd-3.3.0? Can you send me the hello.xsd
schema that you are trying to compile?
