Yes, Perl is notorious for not properly prefixing common macro names
like this - this is the correct place to add them. I can get this
added to the swig runtime files so it will appear their in later
XML-Xerces releases.

The problem is these are pre-processor macros, and so namespaces don't
work.

Ah, let me know what these are. Your strategy of putting #undef's in
Xerces.cpp is the correct one.
