Nesting in $bibliography.collection

[Nigel hardy <nwh@aber.ac.uk>]

I have just had a system break and discovered that it seems to be 
because I introduced bibliodiv elements into the document identified by 
$bibliography.collection. I am using docbook-xsl-1.72.0

 From inspection the XSL seems to back up this observation. It is 
looking for direct children of bibliography.

Is this intended? Am I missing something?

Nigel
