The text I am referring to in 4.2 is

          envid-parameter = "ENVID=" unique-envid
          unique-envid    = local-envid "@" fqhn
          local-envid     = xtext
          fqhn            = xtext
...
                                     In most cases, this means setting
      fqhn to be the fully qualified host name of the system  generat-
      ing  this  ENVID
...

"In most cases" leaves the door open for it not being required.  The
document never says what "fqhn" must be.  By my reading of the document, an
ENVID of "123@6425ChristieAvenueSuite4000EmeryvilleCA94608USA" is perfectly
legal as long as I can guarantee it's uniqueness.
