[FS] error in Variable Reference rule's use of $VarName

4.1.2 Variable References / Dynamic Evaluation
In the rule for an importanted variable, the
premise "dynEnv1 |- $ VarName => Value" should be
"dynEnv1.varValue(expanded-QName) = Value"
Using $VarName is wrong as the two modules may
declare different namespace prefixes.
