[lxml-dev] Validation against an external DTD

[mike at it-loops.com]

Hello, 

I read through the documentation and I did not find a way to validate an 
XML-File against an external DTD with lxml. I searched the ML-archive and 
found several posts but I still do not know exactly, if this functionality 
is available or not.
Right now I am using pyxml to do validation, but since the whole process 
will switch to xml schemes I am looking for a tool that can validate both 
(XSD,DTD).
Is it possible to extend lxml to do this?
I know that I can use a tool like "trang" to convert the DTDs but since 
there are DTDs that get added or removed from the process this means a lot 
of manual work. 

Kind regards,
Michael
