[ZPT] including text/xml templates inside a text/html template changes Content-Type

[Troy Farrell]

Hi guys (and ladies.)
I've observed a most unusual occurance (or perhaps not.)

http://www.studyshare.net/dailyverse/

I have a pt (index_html) that is text/html.  Inside this template, I 
have something like this, twice:

<pre tal:content="here/complex_dv_doc"></pre>

This basically includes another template from the same folder.  In this 
case, complex_dv_doc is a text/xml document which is html quoted 
automatically (because I didn't use structure).  As those of you using 
IE will notice, this results in the Apache <- PCGI <- Zope monster 
returning my html document as Content-Type: text/xml.  Since I use 
Mozilla/Linux all the time, I never noticed until a user told me my site 
had problems :(

My question is this:  Is that normal?  If so, what should I do to fix it?
