We decided in the end to continue to allow %WSP; to appear on its own in
the places it is currently permitted, as there are some scenarios where it
could prove useful. If scanning, then when no white space is present in
the data, a zero length match is returned..

Subject: Allowable usage of entity class %WSP*;
The DFDL spec is very restrictive about the use of %ES; - it is only
permitted as a nil literal value. But the spec does not say anything
about the use of %WSP*; when used on its own - which may equivalently be
written as "%ES; %WSP+;". I don't think that %WSP*; should be allowed on
its own other than for nil literal value. It may of course be used in
combination with other DFDL entities.
