RE: html toc

Try a search for "XSLT positional grouping".

It's much easier in 2.0, using <xsl:for-each-group
group-starting-with="h2">.

In 1.0, think in terms of using xsl:apply-templates to traverse the logical
tree instead of the physical tree. That means that when you're on an h2, you
want to select the logically subordinate h3 elements, which you can do like
this:

select="following-sibling::h3[generate-id(preceding-sibling::h2[1]) =
generate-id(current())]"
