[DFDL-WG] Allowable usage of entity class %WSP*;

[Steve Hanson]

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.
