[dnsext] What is the 'canonical' spelling: RRset of RRSet ?

[Alfred Hönes <ah@TR-Sys.de>]

Folks,
I need a bit of feedback for a review.

What is the correct/preferred spelling/capitalization from the PoV
of the list:  "RRset"  or  "RRSet"  ?

There's a very decided position in the IETF w.r.t. the capitalization
of other important acronyms, like "IPsec".
Do the readers of this list care similarly in the above case?

Background information usage in on selected 'important' DNS RFCs:
o  "RRset" is used in RFCs 4033, 4034, 4035, and 4509;
o  "RRSet" appears in RFCs 2181 and 5155.
o  current DNS related I-Ds also vary; there are even drafts using both.

Any opinions?

Thanks in advance for the help, and
kind regards,
  Alfred.
