[xsd-users] Error: incomplete type when compiling cxx generated with --file-per-type

[Yongchang Huang]

I think I need some coffee. libxsd does not provide .so files actually.

I ignored the previous libxsd doc build error and linked the objects into
executable finally, and successfully parsed a very simple sample xml.

I will continue to try more complex xml with multiple namespaces elements
and open a new case if needed.

Thank you Boris for this new libxsd release!

Thanks,
yohuang
