Yes, you're right of course. I have a similar situation here: the xml  
produced by ooo is too messy, so I want to preprocess it to something  
that is easier to maintain and modify (e.g., I will, at some point,  
add index entries and a TOC); that's why I use xslt here. But I still  
produce xml which I process with mkiv.

Interesting. I have tried to play around with python-lxml, but am  
having some problems to understand it. Just to give me an idea: how  
would you transform this:

<text:span text:style-name="T3">foo</text:span>

to this

<emph>foo</emph>

with lxml? lxml seems to object to the ":" in the tag, even though  
it's declared in the document.
