The problem is that in your first test you are testing for
the value of section when you are already inside the section
element. You want to use '.'. Corrections and hints follow.

If you want to store a string in a variable, it's probably safer
to use (and quicker to parse) something like this

<xsl:variable name="currentsection" select="'other stuff'" />

Then use <xsl:otherwise> to avoid the second test. If you want
the <section> element in your output, use <xsl:copy-of> to
copy the selected node (in this case .) and all of its children.

Hope this helps.
