All I need to do call setContentType("text/xml") from the DomifyView.
The current behavior of all other view types should be fine.

It does seem like a good idea, but I'm not sure it would be used outside
of XSLT (which already allows specifying the output-type).  For document
transforms, the content-type is usually set within the template using
the request.setContentType() method.

If I knew an easy solution, I would probably implement it immediately,
but I suspect a framework-level process for interpreting content-type on
view and transform configuration nodes might be more complicated than it
would be worth.  It might be easier to implement content-type
interpretation on a view-by-view, transform-by-transform basis and
simply provide some tools in the core to make it easier.  Dunno.  Of
course, if you have an elegant solution, you're welcome to make the
changes ;-)

There is enough ambiguity here that my inclination is to follow the
YAGNI principle - we've addressed Mike's specific concern, and if
someone else comes up with a compelling use case then we can revisit the
issue.
