[Serialization] SCHEMA-M

Editorial

[M] [Section 1: Introduction] The key words defined in RFC 2119 are in
uppercase and should be here too and where used as a term of art. e.g.
s/may/MAY s/must/MUST etc. or a note should be added clarifying that the
lowercase forms are always used as terms of art.

On behalf of the XML Schema WG.
