    XSLT Stylesheet DocBook -> LaTeX 

    ############################################################################ -->

     The first <cover> is assumed to be for the front page, the second one is

     for the back page.

     The implementation tries to match the DocBook 4 method that uses

     <mediaobject>s with role='cover' to represent a cover, but it ignores those

     elements if <cover> elements are found.
