# Erlang modules in ejabberd use a custom module attribute [1]
# named -protocol to define what XEPs and RFCs that module implements.
# General protocols are defined in ejabberd.erl
#
# The supported syntax is:
#   -protocol({rfc, RFC-NUMBER}).
#   -protocol({xep, XEP-NUMBER, XEP-VERSION}).
#   -protocol({xep, XEP-NUMBER, XEP-VERSION, EJABBERD-VERSION, STATUS, COMMENTS}).
# Where
#   RFC-NUMBER, XEP-NUMBER :: integer()
#   XEP-VERSION, EJABBERD-VERSION :: atom()
#   STATUS, COMMENTS :: string()
# For example:
#   -protocol({rfc, 5766}).
#   -protocol({xep, 111, '0.2'}).
#   -protocol({xep, 222, '1.2.0', '17.09', "", ""}).
#   -protocol({xep, 333, '1.11.2', '21.09', "complete", ""}).
#   -protocol({xep, 333, '0.2.0', '21.09', "partial", "Only client X is supported"}).
