Version 0.09 of Apache::Template is now on its way to CPAN.  Available
right here, right now:

  http://wardley.org/perl/Apache-Template-0.09.tar.gz

This adds 'type' to the TT2Headers options:

  TT2Headers    type length etag

Note that if you don't specify any TT2Headers option then you get
just 'type' by default (same as 0.08 and before).  But if you are 
currently using TT2Headers then you will now need to explicitly add
'type' if you want the Content-Type sent (or leave it out if you don't).

  TT2Headers    length etag          # v0.08 and earlier - 'type' implicit
  TT2Headers    type length etag     # v0.09 - must add 'type' explicitly

Or you can set it to 'none' and, unsurprisingly, you get none of the 
headers.

  TT2Headers   none

There is also the TT2ContentType option to set a different Content-Type
to the default of 'text/html'.

  TT2ContentType  text/xml

I didn't add anything to do this explicitly because you can currently make 
the request accessible and do it through that:

  TT2Params    request

And then in the template:

  [% IF request.content_type == 'text/html';
       ...
     END
  %]

Not quite as succinct, but it does the job and saves us from having to 
having to add anything to Apache::Template that can't easily be added
in a subclass.

Thanks for the code and ideas!

Cheers
