I'm just looking from a stylesheet perspective and the above template
rule seems not entirely correct to me. I'm wondering why you don't make
it more explicit? Something like this:

  <xsl:template match="slidesinfo/subtitle[1]" mode="subtitle.markup">

I haven't tested it, but I hope it should work. :) 

The above xsl:value-of is unfortunate and not always a good idea. One
example, where the difference becomes apparent:

  <subtitle>The Quick <quote>Brown</quote> Fox</subtitle>

If you use xsl:value-of, you get the complete _string_ of your
subtitle content---without any quotes. The quotes can only appear if you
allow your template to process its child elements. Use
xsl:apply-templates and you will see the quotes.
