No, but “w3.org” is; and the point was to illustrate that 
whether the Owner Identifier used is registered or unregistered 
has nothing to do with whether the source is an officially 
recognized standards organization or not. Anyone who controls an 
Internet Domain Name get to issue Formal Public Identifiers with 
a “+” in them.

Granted the IDN option was added to SGML only as of the WebSGML 
Adaptations Annex, but that's simply because the web made ISO's 
typical practice of acting as a registry for namespace hierarchy 
(cf. SNMP OIDs etc.) un-scaleable for the use the web put FPIs to.

ISO 8879:1989 states that SGML public text owner identifier registration
(i.e., those that start with a + instead of the unregistered -) is defined in
ISO 9070, which I don't have a copy of. I can, however, quote the summary
from ISO 8879:1989: These [registered owner identifiers] include standards
body identifiers for national or industry standards organisations (similar to
the ISO owner identifier), and unique codes that may have been assigned to
organisations by other standards.

Annex K (“Web SGML Adaptations”) to ISO 8879 TC2: [[[

  K.4.6 Internet domain names in public identifiers

  [80] owner identifier =
ISO owner identifier |
registered owner identifier |
unregistered owner identifier |
internet domain name owner identifier

  [83.1] internet domain name owner identifier =
+//IDN , minimum data
  where the minimum data must begin with an Internet domain name.

Note 35: A string like IDN domain.name or IDN
domain.name/sub-domain/sub-domain is treated as an ISO/IEC 9070
registered owner prefix. Any sub-domains of a domain could also
be identified using owner name components. For example, the Internet
domain named someisp.net and its sub-domains in the URL
http://www.someisp.net/users/mtb; could occur in an FPI as:
  
  +//IDN someisp.net::www::users::mtb
  
or as:
  
  +//IDN www.someisp.net/users/mtb
  
Note 36: When constructing a public text owner identifier using
an Internet domain name, users may wish to consider the name's
potential lifespan and the lifespans of the objects to be identified.

  Semicolon, exclamation point, asterisk, number sign, commercial at
  sign, dollar sign, underscore, and percent sign are members of the
  abstract character class special, which is usable in minimum data.
