This specifies revision information to the particular object. There may also be information about previous revisions in order to support resynchronization. In this case, the most actual revision information is the one for the actual object. The actual information can be identified using the attribute
[DATE].
[DATE] must follow one of the patterns in oder to provide a sequenctial order by performing simply a lexical sort.
<YYYY>-<MM>-<DD>[T<hh>:<mm>:<ss>]
<YYYY>.<MM>.<DD>[T<hh>:<mm>:<ss>]
<YYYY>/<MM>/<DD>[T<hh>:<mm>:<ss>]
The last pattern is the most preferred one, since it reflects a common use in US.
