Doc: fix bogus cross-reference link.

Browse Source 
An xref to a <para>'s ID isn't very helpful because paras don't have
names.  This causes a warning while building PDFs, though for some
reason not while building HTML.  The link arguably went to the wrong
place, too.

To fix, introduce a sub-section we can reference.
