[Fedora-packaging] Question regarding min and max dependencies

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 Shawn
