Report of the Ideographic Variation Sequences ad-hoc

The ad-hoc reviewed documents L2/04-219, "Registry for Ideographic
Variation Sequences" and L2/04-336, "About the registry of Ideographic
Variation Sequences", and discussed the following
modifications/clarifications:

For the description of the registry:

- emphasize that the Consortium does not take any responsibility for
  the suitability, completeness, quality, etc. of the collections and
  sequences registered by third parties

- emphasize that users should carefully evaluate whether a collection
  is suitable for their purpose

- clarify that it is possible that the same intent be implemented in
  two different collections, i.e. that two collections can
  independently contain (distinct) sequences which serve the same
  purpose.

For the format of the database:

- collection identifiers and sequence identifiers must be Unicode
  identifiers as defined by UTS 31; furthermore they must contain only
  characters in the range U+0020 .. U+007F.

For the registration of a collection:

- the application must include a written statement that the registrant
  will make reasonable efforts to maintain the stability of the URL
  giving access to the description of the collection

- the registration of a collection is subject to a non-refundable
  processing fee of $200. This processing fee is waived for the first
  5 collections registered or sponsored by a Full member of the
  Consortium during a membership year. A sponsored registration is one
  done by any third party and for which the Consortium member pays the
  processing fee.

- a registration form will be created, covering the items mentioned in
  L2/04-219, the items above, as well as additional questions: to
  ensure that the registrant understood the nature of the registry; to
  remind the registrant that a public review period is strongly
  encouraged, to ask whether this review did happen, and whether all
  the comments received have been addressed.

For the registration of one or more sequences:

- the registration of a sequence is subject to a non-refundable
  processing fee of $1. This fee is waived for the first 2,000
  sequences registered or sponsored by a Full members of the
  Consortium during a membership year. A sponsored registration is one
  done by any third party and for which the Consortium member pays the
  processing fee.

- the registration of sequences must include a suggested variation
  selector to use for the each sequence

- registration of sequences must include a machine readable file, in
  the format of IVD_Sequences.txt, covering all the requested
  sequences
