I didn't know about the <link> tag, thanks for the suggestion. (I
won't claim to be a DocBook expert.)

Can you suggest when <xref> should be used, and when <link> is the
right tag to use?

(The fact that the endterm of the xref must fit into the grammatical
structure of the local sentence doesn't seem like a major problem to
me. If we change the endterm of *any* xref, couldn't that disturb the
xref's local sentence? i.e. don't the existing uses of <xref> in the
docs suffer from the same problem?)
