That's to be expected.  The spec does not specify what the response to
this request should be, or if it is even valid -- so I didn't implement
it.

This happens if you're browsing the URLs in a web browser that supports
xsl directives.  Previous versions of the server supported web browsers,
but at the cost of using a 'text/xml' Content-Type header.  Consensus in
the group was that web browsers are not a target platform, so this feature
no longer works -- so you won't be able to view the DAS2XML in your
browser anymore.  I just haven't removed the XSL references yet.

The server is coded to throw an error if you ask for all features, so I'm
surprised it didn't just give you a 4xx or 5xx response.  I'll look into
it.
