Probably, but not necessarily and regardless, that doesn't help answer 
the question.  The point is that the nc RPM on RHEL does not provide 
"netcat".  Whether it should or not and what it should be called is 

I have the same problem with required the "jre" because Sun's RPMs don't 
give adequate provides information.  The jre RPM provides "jre" and the 
jdk RPM provides "jdk".  The jdk RPM though doesn't provide "jre" even 
though in reality it does include the jre.  The openjdk RPMs (at least 
from RHEL) note that they provide "jre" and also "java", which is 
probably how it should be done.

I'm pretty sure the answer to your question is no.  See 
  Quoting from Josh Kelly's post:

"The standard way to do this is via virtual provides: the providing RPMs 
each state that they provide a virtual package, and the dependent RPM 
requires that virtual package. So, in your example, vim and emacs both 
Provides: text-editor, and your package would Requires: text-editor.

If the packages that you're depending on don't provide an appropriate 
virtual package, you could probably hack around this by making up your 
own. Make dummy my-package-vim-mode and my-package-emacs-mode RPMs that 
Requires: vim and Requires: emacs, respectively, and Provides: 
my-package-text-editor, then have your package Requires:
