[xsde-users] Re: [xsd-users] error processing multiple schemas at once

Hi Eric,

In the future, please send questions about XSD/e to the xsde-users
mailing list instead of xsd-users.

XSDE_SERIALIZER_VALIDATION only controls whether serialization will be
built with validation support or without. But the runtime will always
include the serialization support.

However, if you don't compile any of your schemas with serialization
support, then none of the symbols from the runtime (which is a static
library) will end up in the resulting executable.

There is no way to disable Expat compilation in the XSD/e runtime other
than manually removing the files from the makefile (see 
libxsde/xsde/makefile; there is just one line to comment).
