Hi!

Maybe someone is interested in this patch:

If you have html-tidy[1] installed, you can apply this patch to
lib/python/ZPublisher/HTTPResponse.py to scan every html page with
html tidy.

Warnings of html-tidy will be displayed in the debug logs. 

[1]: http://tidy.sourceforge.net/

You apply this patch like this:

cd zope/lib/python/ZPublisher
cat html-tidy-patch.txt | patch
