The idea that sort of contradicts this is break-before ='page'
on sect2!

perhaps better to stick a blank
<para xml:id='end'/> prior to the major block?

Note the fo constraint above? Using indexterm, a para in the end of
the first sect would be better?

This does look more robust though.

<grin/> I bet Bobs stylesheets shout at you when you do that!

Indexing is a weird topic anyway.
certainly a pretty rare skill IMHO
