   Declaration of syntactic structure:

      urn            := 'urn:' nid ':' name
      nid            := 'urn-' n
      n              := number-assigned-by-IANA
      name           := [A-Za-z][A-Za-z0-9]*

   Examples of valid URNs under this scheme include:

      urn:urn-n:someName
      urn:urn-n:anon05178

   Relevant ancillary documentation:

      The name component is identical to the one found in the W3C's 
      N-Triples specification:-

        http://www.w3.org/2001/sw/RDFCore/ntriples/#name
        - N-Triples, revision 1.9, W3C RDF Core WG Internal Working Draft

      All URNs defined herein conform to:-

        http://www.ietf.org/rfc/rfc2141.txt
        - "URN Syntax", RFC 2141, May 1997, Moats, R.

   Identifier uniqueness considerations:

      These identifiers need to be unique for the context of their use, 
      which is the scope of the quantification for each particular anonymous 
      none. Processors should ensure that the anonymous nodes are indeed 
      unique within their contexts.

   Identifier persistence considerations:

      URNs have the requirement that they be persistently bound to one 
      resource, and not reassigned. Since the scope of these identifiers 
      is a single document, that is easy to ensure.

   Process of identifier assignment:

      Assignment of this URN scheme is fully open, as long as the syntax 
      rules are obeyed. The author of the document gets to choose the 
      identifiers used for the anonymous nodes (indeed, these may be 
      automatically generated, and often are).

   Process for identifier resolution:

      None specified.

   Conformance with URN Syntax:

      Processors MUST follow the lexical equivalence considerations 
      of the URN specification.

   Validation mechanism:

      None specified.

   Scope:

      Global.
