Subject: Re: [docbook-apps] XInclude in sitemap problem
Hi,
I found a solution that might be worth for inclusion in the docbook-xsl distro.
Basically I enclose everything of the ttl and xreftext sections of a target db in a CDATA section. (common/targets.xsl)
Then I ensure that the output of the xreftext is not xml encoded. (common/olink.xsl).
Cheers,
Marco
