/*
 *  Reference:RFC 6020.
 *  The "revision" statement specifies the editorial revision history of
 *  the module, including the initial revision.  A series of revision
 *  statements detail the changes in the module's definition.  The
 *  argument is a date string in the format "YYYY-MM-DD", followed by a
 *  block of sub-statements that holds detailed revision information.  A
 *  module SHOULD have at least one initial "revision" statement.  For
 *  every published editorial change, a new one SHOULD be added in front
 *  of the revisions sequence, so that all revisions are in reverse
 *  chronological order.
