MSIR.0740 AllowNull only allowed for Objects
AllowNull was specified on a method or subroutine parameter in the method or subroutine declaration but the parameter was not an object. Since only objects can be "null", the AllowNull keyword doesn't make sense for other parameter types. Presumably, either the AllowNull keyword wasn't intended or the parameter was intended to have an object type. Correct the parameter declaration.
