%% Purpose: YECC grammar for text encoding of Megaco/H.248
%%----------------------------------------------------------------------

%%----------------------------------------------------------------------
%% Annex B TEXT ENCODING OF THE PROTOCOL (NORMATIVE)
%%
%% B.1 Coding of wildcards
%%
%% In a text encoding of the protocol, while TerminationIDs are
%% arbitrary, by judicious choice of names, the wildcard character, "*"
%% may be made more useful.  When the wildcard character is encountered,
%% it will "match" all TerminationIDs having the same previous and
%% following characters (if appropriate).  For example, if there were
%% TerminationIDs of R13/3/1, R13/3/2 and R13/3/3, the TerminationID
%% R13/3/* would match all of them.  There are some circumstances where
%% ALL Terminations must be referred to.  The TerminationID "*" suffices,
%% and is referred to as ALL. The CHOOSE TerminationID "$" may be used to
%% signal to the MG that it has to create an ephemeral Termination or
%% select an idle physical Termination.
%%
%% B.2 ABNF specification
%%
%% The protocol syntax is presented in ABNF according to RFC2234.  The
%% protocol is not case sensitive.  Identifiers are not case sensitive.

%%----------------------------------------------------------------------
%% Number of expected shift/reduce warnings
%% This is ugly but...
%%----------------------------------------------------------------------

Expect 489.
