could we please have details of how conneg expressions or HTTP
Accept headers could be used to say things like
"I accept XML documents"?
Here is a strawman ...
(a) revise RFC 2295 (currently experimental) so that rather than use its
own notations for describing resource variants and client features it uses
conneg expressions. RFC2295 introduces an "Accept-features:" header that
is provided by a client requesting a resource.
(b) register a conneg feature tag to indicate XML content; I would suggest
something along the lines of (XML-namespace="<URI>"), where <URI> is an XML
namespace identifier, as that would allow negotiation to specific XML
applications. A distinguished value, say "*", would be defined to indicate
a generic XML handling capability. An empty string could indicate XML
handling without recognition of namespaces (i.e. "classic" XML).
(c) use the proposed Content-feature tag for labeling MIME content.
I believe this approach takes far greater account of the way the XML and
XML applications are being developed by W3C than simply having a parameter
that says "this is XML".
