Hi Dan:

True-ish. The hash char is not invalid ­ but it _is_ reserved.So, whatıs the
difference there? Though I guess itıs theoretically useable. This from RFC
2141:

³2.3.2 The other reserved characters


   RFC 1630 [2] reserves the characters "/", "?", and "#" for particular
   purposes. The URN-WG has not yet debated the applicability and
   precise semantics of those purposes as applied to URNs. Therefore,
   these characters are RESERVED for future developments.  Namespace
   developers SHOULD NOT use these characters in unencoded form, but
   rather use the appropriate %-encoding for each character.²

Hard to know what to do.

Cheers,

Tony
