Section 2, pg.2/3 says:
Declaration of syntactic structure:
| The Namespace Specific String (NSS) of all URNs that use the
| "3gpp" NID will have the following structure:
urn:3gpp:{3gpp-urn}
where the "3gpp-urn" is a US-ASCII string that conforms to the
NSS(Namespace Specific String) Syntax described in RFC 2141
| [RFC2141] and defines a specific resource type.
It should say:
Declaration of syntactic structure:
| All URNs that use the "3gpp" NID will have the following
| structure:
urn:3gpp:{3gpp-urn}
where the "3gpp-urn" is a US-ASCII string that conforms to the
NSS(Namespace Specific String) Syntax described in RFC 2141
| [RFC2141] and defines a specific resource.
Notes:
a) Obviously, the original clause contradicts itself.
It is impossible that the NSS is a proper subpart of itself
as would be required by the text and the syntax shown.
The corrected text resolves this partial issue, but not the
next two issues, which still remain open. Furthermore, for
logical consistency, "resource type" had to be replaced by
"resource" in the last line, to maintain the required
uniqueness property of '3gpp' URNs.
b) Even the corrected statement merely is a simple instantiation of
the general definition in RFC 2141 (Section 2, page 1), plus
giving an alias name (<3gpp-urn>) to the NSSs of '3gpp' URNs.
However, it does not cure the apparent underspecification:
The current URN Namespace registration template per BCP 66,
RFC3406, serves for "... providing a mechanism for disclosing
[the] structure of the URN namespace ..." (page 11 of RFC 3406),
but the quoted clause, as it stands, does *not*
"outline any structural features of identifiers in this namespace"
(p. 12 of RFC 3406).
