OK, but again, if you have a better idea, it is welcome. Modifying 12 
templates does not look much better to me.

Looking closer, it was actually the ids that were causing the problem. 
Ids can't start with _ in HTML 4.01 but it is perfectly legitimate in 
XHTML. So, Plone is compliant with XHTML.

The filter runs on the HTTPResponse object, thus changing all the HTML 
output, not just the ouput from main_template.

Well, looking forward, if the NZ government guidelines finally support 
XHTMl, we'll just need to remove the filter.

In addition, we want to be able to transform the content with XSL 
transformations.

Finally, Kupu and Epoz are good at producing XHTML, but don't support 
HTML 4.01.

Before, i had to modify 10-12 templates at least. Between Plone 2.0.4 
and 2.0.5, these templates got changed and I had to spend 20 hours or so 
reworking the HTML ouput and testing.
Now, when we move to Plone 2.1, I hope to do no work at all. I don't 
think it is a myth :-)
