[xsd-users] Extract common type definitions to a separate header

[Yury Zaytsev]

Hello,

I'm using XSD on a biggish schema of the order of magnitude of thousands 
of types. Since the schema is rather large and the definition spans many 
files with circular dependencies, I've opted for the excellent 
"--file-per-type" mode.

However, I've noticed that every header file for the generated entities at 
the very beginning has a section that defines common types by including 
XSD runtime headers and populating the xml_schema namespace:

     #include <xsd/cxx/version.hxx>

     ...

     namespace xml_schema
     {
        ...
     }

As far as I can see (I could have easily missed something though), this 
code is completely stereotypical and same for all headers.

If this is indeed the case, then putting these 5 Kbs into a separate 
header will shave off some 5 Mbs for a thousand types and will make the 
generated code much smaller and the compilation much faster.

In addition, I could include this header instead of <root_type-fwd.hxx> to 
get just xml_schema::exception, etc.

Could this feature be possibly considered for implementation?

All the best,
