profile.lang and docbook slides

Hi all,

  I am trying to select a profile based on long on a slides document
(v3.4.0). Reading the documentation at:

http://docbook.sourceforge.net/release/xsl/current/doc/fo/profile.lang.html

  It seems the I need a specific profiles for each type of document. I
could not find no profile.xsl in the docbook-slides distribution. Has
anyone done any profiling on docbook-slides ?

Thanks a bunch
