ANNEX C TAGS FOR MEDIA STREAM PROPERTIES (NORMATIVE)

   Parameters for Local descriptors and Remote descriptors are specified
   as tag-value pairs if binary encoding is used for the protocol.  This
   annex contains the property names (PropertyID), the tags (Property
   Tag), type of the property (Type) and the values (Value).Values
   presented in the Value field when the field contains references shall
   be regarded as "information". The reference contains the normative
   values.  If a value field does not contain a reference then the
   values in that field can be considered as "normative".

   Tags are given as hexadecimal numbers in this annex. When setting the
   value of a property, a MGC may underspecify the value according to
   one of the mechanisms specified in section 7.1.1.

   For type "enumeration" the value is represented by the value in
   brackets, e.g., Send(0), Receive(1).
