DOCBOOK: xref accross imported files when using slides

[Christoph Steinbeck <steinbeck@ice.mpg.de>]

Hi, 

I'm trying to use <xref> to point to a bibliography entry in a slide
(based on slides.dtd).
The whole mechanism works fine with the regular docbook html
stylesheets, so maybe this is related to the use of slides.dtd and the
associated stylesheets. 

Anyway, I have central slides.xml file, which imports the
bibliograph.xml as an entity. 
This bibliography.xml contains   <biblioentry id="helson99"
xreflabel="helson99">...</biblioentry>
When trying to do <xref linkend="helson99"/> in the central slides.xml
file, I get the error "XRef to nonexistent id: helson99".

Any workaround for this? Or am I doing something wrong?

Cheers, 

Chris
