Hi Simon
As far as I can see: your requirements can be met with XML.
Please let me know if we can be of assistance in working this out.
Henning

Betreff:	Re: AW: work on url for television started

Throwing in a generic look at URIs, namespaces, and "looking into" a
resource to see what it contains:

"Namespaces in XML" World Wide Web Consortium Working Draft
16-September-1998

at
http://www.w3.org/TR/WD-xml-names

This is a proposed general solution to using URIs in namespaces, which could
be a way to "point into" resources.

This "pointing into"/namespace could be a "channel space", stream, or data
cache.  This may be a more flexible tool than URIs alone (particularly if
you assume that the resource pointed into could contain structured data
itself, say an XML data structure).

Rather than hardwire all possible resources, available
sessions/sessions/stream/cache resources may need to be queryable, and the
namespace identifier may need to be separable from the authored content.

Such an approach may offer greater flexibility, authorability, and resource
abstraction.

Rob
