Dear Boris and all,
i'm having some difficulties on a win32 platform (7), with 3.3 version 
of xsd, trying to exporting the symbols for a generated
dll (i use visual studio 9.0 to compile and i create the c++ class by 
command line).

The schema i use are available for download at 
http://www.mxb.it/enigmahc/mxm.zip

The myexport.hxx includes my export definition. I've also added the 
preprocessor info "MXM_EXPORTS".

If i don't export any simbols i got no trouble.

If i export the symbols I can create the c++ class, but when i try to 
compile i found a lot of this kind of error:

1>VideoType.cxx
