[xsd-users] problem with xerces namespace

[Boris Kolpackov]

Hi Denny,

[I've CC'ed xsd-users to my reply since others may encounter a similar
 problem in the future.]

You seem to define a macro called X (probably for handling XMLCh to char
conversions) which interferes with template arguments used in the XSD
runtime headers. I've ran into the same problem[1] with XQilla not long
ago.

The way to get rid of this problem is to make sure that you include
the header that defines the X macro after you include the generated
headers. We will also use a different name for this template argument
in the future releases of XSD seeing that it is causing problems. If
you would like I can send you the XSD runtime with this change.
