Re: [docbook-apps] xslt for imageobject link

[Bob Stayton <bobs@sagehill.net>]

Hi Fredrik,
I think you could replace the risky $object.index+1 with 
@condition='original' in the predicate for $link.

The extra namespace declaration can probably be eliminated by making 
sure your customization layer adds "d" to the list of namespace prefixes
in the exclude-result-prefixes attribute of the xsl:stylesheet element.
