Request for Token Expression for Feature and Characteristic Parameters

[samgambrell]

Elements 'ArithmeticFeatureParameter' and 'ArithmeticCharacteristicParameter' allows for pulling an arithmetic value from a Feature or Characteristic using xpath for use in an Arithmetic Expression.
Requesting similar elements to allow for the same functionality with Tokens (ex: 'TokenFeatureParameter' and 'TokenCharacteristicParameter') for use as a Token Expression.
This will allow for QIF rules to also be built around tokens (ex: CharacteristicDesignator\Criticality\LevelEnum).

[samgambrell]

Above situation should also incorporate the functionality of 'ArithmeticPartParameter' and 'ArithmeticDMEParameter'.
In addition to Token the following capability should also be added to Boolean types. (ex: 'BooleanFeatureParameter')

These all seem like useful additions to me. The rules model was devised (mostly by me) to enable modeling specific rules that were known to be in use. Where there is demand for additional capabilities in the rules model, I think the demand should be met, provided there is no insurmountable modeling problem. I do not think the suggested additions will face any modeling problem.

BooleanConstantEnumType already exists in GenericExpressions.xsd and can be used for testing against a BooleanFeatureParameter or BooleanCharacteristicParameter. TokenConstantType also exists already.
