Does anyone know if it is legal to write an app which links against both Qt (open-source edition) and an Apache module, like Xerces, which uses the Apache 2 licence? I understand there are incompatibilities between the A2L and the GPL because the A2L has a termination clause which is triggered by someone launching patent suits against Apache contributors.

The thing is I need a XML validation library, which Qt doesn't have. Can anyone help?

You should (must?) not combine software of both licenses: http://www.apache.org/licenses/GPL-compatibility.html

You could use libxml2: http://xmlsoft.org
A search on freshmeat will probably return some more results.

I guess there is possibility if you load the apache module as plugin for your GPL application in run-time.
