OK.  That was a bug then.

Right.  This is just horribly fragile.  There are all sorts of things
that could go on in the stylesheets that could cause this not to work. 
Generally speaking, disable-output-escaping is best avoided.  Also note
that an XSLT processor is not required to support it, so even if it did
work, there's no guarantee your XSLT will work elsewhere.

Create a stylesheet that imports Norm's stylesheets with

<xsl:import
href="http://docbook.sourceforge.net/release/xsl/current/html/docbook.xsl"/>

Then look at chunk-common.xsl in Norm's stylesheets and copy the
template chunk-element-content.  Change it to your liking.
