Is it valid to use 2 requires of the same dependency for min / max versions?  For example, I have a package "foo" that depends on package "bar" >= 1.0 and also "bar" < 2.0.

I have seen many packages use this:
Requires: bar >= 1.0
Conflicts: bar >= 2.0

but I would like to use the following (which may help with finding dependencies using repoquery):
Requires: bar >= 1.0
Requires: bar < 2.0
