That's good news!

First, most of the Xerces-C code was written by IBM people, once in
silicon valley, now in Toronto. I've added very little code to the
project. I maintain the Perl port.
I've never completely understood the FOO_EXPORT stuff. Part of it is
resolved in util/XercesDefs.hpp and part in you compiler's *Defs.hpp
file.
Heres the part from XercesDefs.hpp:
#if defined(PROJ_SAX4C)
#define SAX_EXPORT PLATFORM_EXPORT
#else
#define SAX_EXPORT PLATFORM_IMPORT
#endif
and here's the piece out of util/Compilers/VCPPDefs.hpp:
// ---------------------------------------------------------------------------
// A define in the build for each project is also used to control whether
// the export keyword is from the project's viewpoint or the client's.
// These defines provide the platform specific keywords that they need
// to do this.
// ---------------------------------------------------------------------------
#define PLATFORM_EXPORT __declspec(dllexport)
#define PLATFORM_IMPORT __declspec(dllimport)
So it looks like the macro isn't getting resolved properly on
Windows. On Linux PLATFORM_EXPORT/IMPORT are both empty strings so it
works regardless.
