Re: [docbook-apps] XSL custom chunk with navigation. e.g. legalnotice

["Bob Stayton" <bobs at sagehill dot net>]

I think you pinpointed the problem:

<xsl:variable name="up" select="parent::*"/>

This assumes that the parent element is a chunk. Instead, it should confirm
that the parent is a chunk element, and, if not, then scan backwards through
the list of ancestors until it finds a chunk element.
