Dear iCalendar experts (bcc iana@iana.org, cc jcardcal@ietf.org):

Please review the following registration for a new iCalendar value
data type of "UNKNOWN". (Because Cyrus Daboo is one of the authors of
the specification that registers this value data type, I assume that
Bernard Desruisseaux will need to review the registration request.)

The jCal specification (draft-ietf-jcardcal-jcal) provides the
following description:

   In jCal, a new "unknown" property value type is introduced.  Its
   purpose is to allow preserving unknown property values when round-
   tripping between jCal and iCalendar.  To avoid collisions, this
   specification reserves the UNKNOWN property value type in iCalendar.
   It MUST NOT be used in any iCalendar as specified by [RFC5545], nor
   any extensions to it.

The completed registration template follows (where "RFCTODO" is a
placeholder for the RFC number issued to draft-ietf-jcardcal-jcal).

###

   Value name:  UNKNOWN

   Purpose:  To allow preserving unknown property values during round-
      tripping between jCal and iCalendar.

   Format definition:  (Not applicable)

   Description:  The UNKNOWN value data type is reserved for the
      exclusive use of the jCal format RFCTODO.  It MUST NOT be used in
      plain iCalendar [RFC5545].

   Example:  As this registration serves as a reservation of the UNKNOWN
      type so that it is not used in iCalendar, there is no applicable
      iCalendar example.  For examples of its usage in jCal, see RFCTODO

###

Please let us know if you have any questions, concerns, or feedback.

Thanks!

Peter (JCARDCAL WG co-chair and jCal shepherd)
