Declaration of syntactic structure:
	The identifier structure is as follows:
	URN:<assigned number>:<FQDN>:<assigned string>
	URN:dtg

Relevant ancillary documentation:
	Definition of domain names, found in:
	P. Mockapetris, "DOMAIN NAMES - IMPLEMENTATION AND
SPECIFICATION",
	RFC 1035, November 1987.

Identifier uniqueness considerations:
	Uniqueness is guaranteed as long as the assigned string is never
reassigned for a given FQDN, and that the FQDN is never reassigned.

Identifier persistence considerations:
	Persistence of identifiers is dependent upon suitable delegation
of resolution at the level of "FQDN"s, and persistence of FQDN
assignment.

Process of identifier assignment:
	Assignment of these URNs is delegated to individual domain name
holders (for FQDNs).  The holder of the FQDN registration is required to
maintain an 	entry (or delegate it) in the DDDS. Within each of these
delegated name partitions, the string may be assigned per local
requirements.

Process for identifier resolution:
	Domain name holders are responsible for operating or delegating
resolution servers for the FQDN in which they have assigned URNs.

Rules for Lexical Equivalence:
	FQDNs are case-insensitive.  Thus, the portion of the URN
	URN:dtg
	is case-insensitive for matches.  The remainder of the
identifier must be considered case-insensitive also.

Conformance with URN Syntax:
	No special considerations.

Validation mechanism:
	None specified.

Scope:
	Global.
