The ZPT processor/renderer shouldn't dictate this as it is clear that
ZPTs can be used to create a wide variety of types of content.

I think the content-type sent to the browser should be controlled by
the <browser:page> directive.  The HTTP content-type is really part of
the browser interaction and not necessarily part of the template
processing.  <browser:page> could default to text/html or text/xml or
whatever people decide is the most commonly desired type and include
an attribute to override it.

Hypothetically speaking, because I don't have any relevant experience
to support this, a different type of view may want to use the same ZPT
with a different content-type.  Maybe the XML-RPC or WebDAV publishers
have different constraints and want to send application/xhtml+xml for
a given template while the browser publisher must degrade it to
text/html for IE.
