Improve the resolve-uri function to go through the XML catalog?
0%
Description
Looking at the XSLT specification (both 2.0 and 3.0) it does not seem to explicitly say that certain XSLT functions should resolve through the XML catalog or not. The document() function resolves through the XML catalog but the resolve-uri function does not (from what I looked in the implementation code) although maybe it would be useful if it did.

There's a nomenclature problem here: "resolve" is used both to mean making a URI absolute, and fetching the resource identified by a URI. The fn:resolve-uri() function is very explicitly about making it absolute, The spec says very explicitly
Resolving a URI does not dereference it. This is merely a syntactic operation on two ·strings·.

Note that the XmlResolver library is much more closely integrated into Saxon in Saxon 11. I don't think the library offers an option to "rewrite" a URI based on the catalog without actually fetching the resource - Norm will know!

I don't think we could justify making resolve-uri() interrogate the catalog.

Ok. Then you can probably close this request.

It would be possible to write an extension function to do this, FWIW.
