You're still only touching the variable-initialization case, which seems
like the least important place to document it. I'd have put it with
the assignment-statement documentation. Perhaps something like
<note>
<para>
Here, and in other contexts such as variable initialization,
the assignment operator can be written <literal>=</> as well
as <literal>:=</>. The latter is the preferred spelling, though.
</para>
</note>

AFAIR, we have some of both, and I'm fine with that status quo.
