Is there an OR condition for requires:?

[doc]

For Debian packages, their Depends: tag allows for an "or" condition during installation, such as

Depends: a, b, c | d, e

Does something like that exist for the requires: tag in RPM?   Google hasn't been much help.   This situation is I have one rpm that I want to use for SuSE and CentOS/RedHat.   The problem is on CentOS/RedHat the requirement is "nc."  On SuSE, nc is know as  "netcat."

Hence,  I'm looking for something similar to the following:

requires:  nc | netcat
