+-- ANNEX A: BINARY ENCODING OF THE PROTOCOL (NORMATIVE) 
+-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
+--     
+-- This Annex specifies the syntax of messages using the notation 
+-- defined in ASN.1 [ITU-T Recommendation X.680 (1997): Information 
+-- Technology - Abstract Syntax Notation One (ASN.1) - Specification of 
+-- basic notation.]. Messages shall be encoded for transmission by 
+-- applying the basic encoding rules specified in [ITU-T Recommendation 
+-- X.690(1994) Information Technology - ASN.1  Encoding Rules: 
+-- Specification of Basic Encoding Rules (BER)].  
+--     
+-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
+-- A.1 Coding of wildcards 
+-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
+--     
+-- The use of wildcards ALL and CHOOSE is allowed in the protocol.  
+-- This allows a MGC to partially specify Termination IDs and let the 
+-- MG choose from the values that conform to the partial specification.  
+-- Termination IDs may encode a hierarchy of names.  This hierarchy is 
+-- provisioned. For instance, a TerminationID may consist of a trunk 
+-- group, a trunk within the group and a circuit.  Wildcarding must be 
+-- possible at all levels.  The following paragraphs explain how this 
+-- is achieved. 
+--  
+-- The ASN.1 description uses octet strings of up to 8 octets in length 
+-- for Termination IDs.  This means that Termination IDs consist of at 
+-- most 64 bits.  A fully specified Termination ID may be preceded by a 
+-- sequence of wildcarding fields.  A wildcarding field is one octet in 
+-- length.  Bit 7 (the most significant bit) of this octet specifies 
+-- what type of wildcarding is invoked:  if the bit value equals 1, 
+-- then the ALL wildcard is used; if the bit value if 0, then the 
+-- CHOOSE wildcard is used.  Bit 6 of the wildcarding field specifies 
+-- whether the wildcarding pertains to one level in the hierarchical 
+-- naming scheme (bit value 0) or to the level of the hierarchy 
+-- specified in the wildcarding field plus all lower levels (bit value 
+-- 1).  Bits 0 through 5 of the wildcarding field specify the bit 
+-- position in the Termination ID at which the starts. 
+--  
+-- We illustrate this scheme with some examples.  In these examples, 
+-- the most significant bit in a string of bits appears on the left 
+-- hand side. 
+--  
+-- Assume that Termination IDs are three octets long and that each 
+-- octet represents a level in a hierarchical naming scheme.  A valid 
+-- Termination ID is 
+--      00000001 00011110 01010101. 
+--  
+-- Addressing ALL names with prefix 00000001 00011110 is done as 
+-- follows: 
+--      wildcarding field: 10000111 
+--      Termination ID: 00000001 00011110 xxxxxxxx. 
+--  
+-- The values of the bits labeled "x" is irrelevant and shall be 
+-- ignored by the receiver. 
+-- 
+-- Indicating to the receiver that is must choose a name with 00011110 
+-- as the second octet is done as follows: 
+--      wildcarding fields: 00010111 followed by 00000111 
+--      Termination ID: xxxxxxxx 00011110 xxxxxxxx. 
+--  
+-- The first wildcard field indicates a CHOOSE wildcard for the level 
+-- in the naming hierarchy starting at bit 23, the highest level in our 
+-- assumed naming scheme.  The second wildcard field indicates a CHOOSE 
+-- wildcard for the level in the naming hierarchy starting at bit 7, 
+-- the lowest level in our assumed naming scheme. 
+--  
+-- Finally, a CHOOSE-wildcarded name with the highest level of the name 
+-- equal to 00000001 is specified as follows: 
+--      wildcard field: 01001111 
+--      Termination ID: 0000001 xxxxxxxx xxxxxxxx . 
+--  
+-- Bit value 1 at bit position 6 of the first octet of the wildcard 
+-- field indicates that the wildcarding pertains to the specified level 
+-- in the naming hierarchy and all lower levels. 
+--  
+-- Context IDs may also be wildcarded.  In the case of Context IDs, 
+-- however, specifying partial names is not allowed.  Context ID 0x0  
+-- SHALL be used to indicate the NULL Context, Context ID 0xFFFFFFFE 
+-- SHALL be used to indicate a CHOOSE wildcard, and Context ID 
+-- 0xFFFFFFFF SHALL be used to indicate an ALL wildcard. 
+--  
+-- TerminationID 0xFFFFFFFFFFFFFFFF SHALL be used to indicate the ROOT 
+-- Termination.

+-- Digit maps and path names 
+-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
+--  
+-- From a syntactic viewpoint, digit maps are strings with syntactic 
+-- restrictions imposed upon them.  The syntax of valid digit maps is 
+-- specified in ABNF [RFC 2234].  The syntax for digit maps presented 
+-- in this section is for illustrative purposes only. The definition of

+-- between the two.
