::PROBLEM
In (X)HTML output, subtitle for the simplesect element generates an
h2 head, no matter at what level in the sectioning hiearchy the
simplesect occurs; end up with cases where a simplesect is
output with (for example), an h4 title but a h2 subtitle
::CAUSE and FIX
No template for simplesect/subtitle in the set of templates that
call the section.subtitle named template, so stylesheets fell
back to using the titlepage.mode template for subtitle
::FIX
Added simplesect/subtitle to the set of templates that
call the section.subtitle named template.
::AFFECTS
Only affects (X)HTML output of simplesect/subtitle; nothing else
