Perhaps I miss something, but I sure can't see the reasoning in the archives
why Provides: and Requires: (which is Depends: for *.deb) cannot be unified.

After refreshing my memory by rereading the larchives, I remember the 
discussions of dependency
alternation that migh affect this suggestion. Can we get an explicit 
example of an "or" relation
in XML somehow.

Seth: Try XML for a package like initscripts, with multiple triggers. 
While most dependencies
in rpm are implictly &&, triggers are implicitly ||. While that detail 
(and triggers themselves)
might remain hidden in the semantic details of packaging, that is a 
place within *.rpm where
a reasonable example for || syntax might be attempted.
