I have a couple of browser views that are trying to render XML and getting

I realize this isn't really a bug, but how DOES one set a mime-type on a
browser view? There doesn't seem to be anything in the ZCML<view>
definition. Because the ISO 19139 xml tags I'm trying to use are mixed
case, but the template is being processed as text/html, the mixed-case tags
below are being rendered in lowercase - and then my xsl stylesheet doesn't
work. If I put the<?xml-stylesheet?> tag into the viewlet, it would
probably actually look like it worked, but the raw XML would still be wrong,
since those tags really are mixed-case.
My view template is simply:
<?xml version="1.0" encoding="iso-8859-1" ?>
<?xml-stylesheet type="text/xsl" href="++resource++ISO2text.xsl" ?>
<div tal:replace="structure provider:MetadataViewlets"
xmlns:tal="http://xml.zope.org/namespaces/tal";
/>
while the code included by the viewlet manager starts:
<mcp:MD_Metadata
xmlns:ns1="http://www.opengis.net/gml/";
xmlns:tal="http://xml.zope.org/namespaces/tal";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:mcp="http://bluenet3.antcrc.utas.edu.au/mcp";
xmlns:gco="http://www.isotc211.org/2005/gco";
xmlns:gmd="http://www.isotc211.org/2005/gmd";
xmlns:srv="http://www.isotc211.org/2005/srv";
xmlns:gts="http://www.isotc211.org/2005/gts";
gco:isoType="gmd:MD_Metadata">
<gmd:fileIdentifier>
<gco:CharacterString tal:content="context/id" />
</gmd:fileIdentifier>

You probably need to set the Content-Type HTTP header in the
response...here's an example from
http://svn.plone.org/svn/plone/Plone/branches/3.3/Products/CMFPlone/skins/plone_templates/rss_template.pt
--
<metal:block tal:define="dummy
python:request.RESPONSE.setHeader('Content-Type',
'text/xml;;charset='+context.plone_utils.getSiteEncoding())" />
Instead of doing this in the template, I'd do it in the view itself. e.g.:
class MyView(object):
def __init__(self, context, request):
self.context = context
self.request = request
def __call__(self):
self.request.response.setHeader('Content-Type',
'text/xml;;charset="utf-8"')
return self.index() # render template associated in ZCML
(You can look up the site encoding if you'd like, but it's going to be
utf-8 in virtually all situations. After speaking to Hanno about this
I've made the utf-8 assumption explicit in my code most of the time.)
