Which I do not understand what it is.

Yes. <Link> elements will be allowed to include <URI> elements and
<TemplateURI> elements. So a <TemplateURI> could be used as a resource map,
but that meaning is very much application specific. There is no such thing
as a generic URI map. The map must always have a very clear semantic
meaning. In /site-meta, when used with rel="describedby", it offers a way to
go from the R-URI to the D-URI. Any other rel and the meaning is undefined.

Anything you want. I only care to define the semantic meaning of
rel="describedby" as my "application" is a generic descriptor method.

See my previous reply to Brian and the above information.
