DOCBOOK-APPS: How to insert an entity via XSL

Hi folks,

I'm using ArborText Epic with our custom DTD to create XML files. Instead of inserting file system references to graphics it takes all paths and create entities for each of those. These entities are then used to identify the graphics.

So, I'm writing some XSL, but I can only get the entity _names_ from the elements. How do I insert the value of the entity in the output stream. Theoretically, I'm looking for something like:

<xsl:entity name="entityname"/>

I know this is sort of off-topic on a DocBook list, but this is where I've found the most XSL skill.

Thanks,
Claus
