Perhaps clarity is simply obtained by noting that whenever
Content-Base and Content-Location are found to have equal predence,
the tie should be broken by giving precedence to Content-Location.

This eliminates all the concern about explaining about header sets, et

It also is independent of how the tie was discovered, whether found in
the local MIME part, or by searching outward for scope.

This looks very nice and tidy to me;-)...\Stef

}is combined with the Base.
