Remarks

Normally, string parameter can not be part of a system of equations. In rare cases that information has to pass in a system of equations by means of a string value, the relation determining the string value can be included in the system since the Solver will remove this degree of freedom via substitution. This implies that any occurrance of this string in the right term of expressions will be substituted with the right term of the string's relation.
