<DL>
<DD>From WFS Spec:  The version attribute is included in order to
 accommodate systems that  support feature versioning. A value of ALL
 indicates that all versions of a feature should be fetched. Otherwise
 an integer, n, can be specified  to return the n th version of a
 feature. The version numbers start at '1'  which is the oldest version.
 If a version value larger than the largest version is specified then
 the latest version is return. The default action shall be for the query
 to return the latest version. Systems that do not support versioning
 can ignore the parameter and return the only version  that they have.
 
 <p>
 This is ready for use, it will be up to data store implementors to
 support it.
