They are required whenever you need to compile documentation, but the path to 
the DTDs/XMLT will be discovered and hardcoded (like now), so exporting them 
shouldn't be needed. But there are two possible consumer for them:
- the xmlcheck plugin for kate (kdesdk) which needs to be touched anyway 
because refers to the internal copy of XML DTDs, and
- the docbook exporter for umbrello, which does the same for xslt.

Is it possible to specify a custom success message, other than the failure 
message?

Which component/function sets xyz_FIND_QUIETLY, then?

Thanks, I was not sure about how the handle this in a portable way.
