The intent of the current draft is to only mention the xpointer()
scheme with respect to these two idioms; referencing the WD there
makes a lot of sense.

Other than that, XPointer support (generically) has been
capital-letters OPTIONAL in the existing recommendation, and there
has been no proposal to change that.  Given that (theoretically),
xpointer() could still move to Rec, I wonder if we should say
anything more?

There's no intent to attribute that behavior to the XPointer
Framework rec: Rather, it's a property of XML Signature's processing
model for same-document references, see point 5 in section
