Wow, I was not aware that there is a SOAP-based flavour of
GetFeatureInfo that requires a WSDL. I think your point is that Manifold
does not support GetFeatureInfo [1].

This sounds like re-inventing the wheel. See [1] for suggestions on how
to work around this. You could also contact Manifold support and suggest
they add GetFeatureInfo (hey, you paid for that software), or replace
Manifold with some GetFeatureInfo capable WMS like Geoserver or UMN
Mapserver.
