Hello!
I've found duplicate aliases of the same OID in
draft-ietf-pkix-new-part1-01.txt
sha-1WithRSAEncryption (section 7.2.1) and sha1WithRSAEncryption
(elsewhere).
The first variant was also found in rfc2632, rfc2633 (along with the
second variant).
Second variant was also found in draft-ietf-smime-certdist-04.txt,
draft-ietf-smime-examples-03.txt and rfc2633.
There are also numerous duplicate OID aliases, for example
PKCS#9-relaeted; they are different in PKIX documents, S/MIME
documents and PKCS#9 itself.
I've found it writing my ASN.1 code to work with S/MIME messages and
X.509 certificates. Having multiple names of a same OIDS is much worse
than having one, I think both workgroups should take care of that.
