I am not at all sure that there’s a single useful XML representation of
any given RDF graph, let alone of RDF graphs in general. For sure there
were better attempts than RDF/XML, ones that did not confuse XML
namespaces (the syntax layer) with naming authorities (the semantic
layer). The XML Information Set has individual characters represented,
rather than strings, which makes querying rather more complex than it
could be.

It might be that a serialization option from XDM instances to RDF could
be defined.

In general it’s not always easy to see how to go from RDF to XML (for
example, what to do if RDF property names or values contain non-XML
characters such as NUL) but i think it's definable if one does not
require a stable round trip to produce the same XML each time.

So in that case, maybe RDF (JSON-LD?) could be added to serialization.
How widely do you think it would be used?

Maybe it would be better done in the expath group?

best,
