One workaround (other than being careful) would be to write
<xref linkend="foo"></xref>
and maintain that style until the last SGML-based version goes EOL.
Another workaround would be to backpatch a check that greps for
something like '[^<]/>' in *.sgml and errors on that.
Just to classify the impact: afaik we use the 'empty tag' technique for
the three docbook tags 'xref' (>3000 times), 'co' (7 times), and
'footnoteref' (4 times).
