As far as I can see from looking at the code, the stylesheets seem
to support generating @title output from two forms of markup:

  - an <alt> child on any element -- e.g.,
    <ulink...><alt>foo</alt></ulink> (see the simple.xlink
    template in html/inline.xsl file)

  - an xlink:title on any linked element, which basically means
    any element that has an xlink:href attribute --
    e.g., <link xlink:href=... xlink:title=...> (see the
    match="*" mode="html.title.attribute" template in the
    html/html.xsl file)

Documentation on xlink:href and xlink:title and the other linking
attributes is here:

  http://docbook.org/tdg5/en/html/ref-elements.html#common.linking.attributes

If your source document is an un-namespaced DocBook 4 document,
you can't use xlink:href or xlink:title, but you can use
<ulink...><alt>foo</alt></ulink>. That's not valid in DocBook 4,
but that doesn't need to prevent you from using it. The
stylesheets themselves are agnostic about validity.
