Correct this is exactly what I mean thank you Paul but not quite so
complex. (bet you didn't expect that!)

I am not very good at explaining things but stick with me..

imagine we did just this

<var class="duration">2:23</var>

this is our variable the thing we want to do something with, in your
example you insert el where the <var></var> is, we want the same, an
insert function to work not a page load  action but on a people or
machine action

If it were a machine that passed by our var duration it would be hoped
that the function would be to do a string replace and re-present the
data as PT2M23S but truthfully this is too much for us to expect from
our humble parser.

so how do we pass the information to a machine....

<var class="duration" title="PT2M23S">2:23</var>

... the Microformats community are used to passing data to a machine via
the @title its a lot more simple than doing a string replace on the
contents of our var. 

in xsl I can now do something like this

<xsl:if test="/*//xhtml:var[@class='duration'] != 0">
select="/*//xhtml:var[@class='duration']/@title" /></duration>

which is my simple function.

This is what I mean by using a Semantic Equivalent.
