This validator requires that I post the code to some host.
The contents that I'd like to verify is intranet contents, which I am
not allowed to post to an external site.

Basically I want to integrate this into a django unit test.

I noticed, that some of of the templates generate documents with
mismatching DTD headers / contents.
All of the HTML code is parsable as xml (if it isn't it's a bug)

There are also some custom XML files, which have their specific DTDs

So I thought about validating some of the generated html with lxml.

the django test environment allows to run test clients, which are
supposedly much faster than a real http client.
