   Declaration of syntactic structure:

      URNs assigned by Web3D will have the following hierarchical
      structure based on the group's organizational structure:

         urn:web3d:{subgroup}:{subgroup-specific string}

      where "subgroup" corresponds to an official Web3D subgroup or
      activity such as the VRML standard ('vrml97'), Extensible 3D
      ('x3d'), Universal Media Working Group ('media'), Geographical
      VRML Working Group ('geovrml'), Humanoid Animation Working Group
      ('hanim') and so forth, and "subgroup-specific string" is a US-
      ASCII string that conforms to URN Syntax requirements ([RFC 2141]).

      In cases where ownership or management of a resource is shared by
      multiple Web3D subgroups or activities, a general category may be
      used in place of a specific subgroup.

      Chairs of Web3D subgroups and activities assign all unique
      identifiers that fall within the scope of the subgroup or activity
      that they chair.  Chairs of Web3D subgroups and activities are
      also responsible for publishing the specific structure of URNs
      assigned by their group or activity.
