No, this is not a spam email. :-) While running some XHTML build tests
today, I noticed a couple of warnings like these:
Request for title of element with no title: literal
Request for title of element with no title: link
After debugging, to begin with the conclusion, we found these are
annoying but harmless. But I'd like to get rid of them, anyway, if
possible. :-)
The ???TITLE??? things in the output come from constructs that attempt
to link to a <bridgehead>. For example, in one of our files:
<para>
The join type. For descriptions of the different types, see
<link linkend="explain-join-types"><literal>EXPLAIN</literal>
Join Types</link>.
</para>
That links to:
<bridgehead id="explain-join-types">
<literal>EXPLAIN</literal> Join Types
</bridgehead>
The link becomes this in the output HTML:
<p>
The join type. For descriptions of the different types, see
<a class="link" href="#explain-join-types" title="8.2.2. ???TITLE???
Join Types"><code class="literal">EXPLAIN</code>
Join Types</a>.
</p>
So the ???TITLE??? becomes part of the title that is displayed if you
hover the mouse over the link, but is not otherwise visible. (That's why
it's harmless.)
Each of the ???TITLE??? instances corresponds to the presence of a
<literal>something</literal> in the link content. No idea why the
stylesheets don't just use the text of the literal in the title
attribute value.
Does anyone have an idea what might be going wrong?
Cheers,
Stefan
