xml2rfc rpm

[Robert Moskowitz]

I see the following rpms in the repo:

# grep xml2rfc dnf.lst
python2-xml2rfc.noarch 2.5.2-4.fc28                    fedora
python3-xml2rfc.noarch 2.5.2-4.fc28                    fedora

yet:

# dnf install xml2rfc
Last metadata expiration check: 2:22:41 ago on Sun 03 Jun 2018 05:33:23 
PM EDT.
No match for argument: xml2rfc
Error: Unable to find a match

And anyway this is old, as I have xml2rfc-2.6.1.tar.gz from back last 
August.

The IETF page: https://tools.ietf.org/tools/

says

There's a tutorial available on how to install from PyPi, or if you're 
impatient you can try the following commands on the command line:
   pip install xml2rfc
if that fails:
   easy_install pip
   pip install xml2rfc
if that fails, go to the tutorial above.


What is the recommended way to install this?  I got to get working on a 
BUNCH of drafts this week....

thanks
