    Suggest reference mode to cover formatted strings

     Hi,

    Scrolling through the list of  currently available (May CTP) reference mode options, I'm wondering if a option for generic formatted strings would be useful.  Creating a model to compare approaches in another thread, I sub-typed email addresses, phone numbers and postal addresses.  I gave the super-type the RM of ".code" as that seemed like the best available fit.  I figure the generated database would use a VarChar type.  

    What are your thoughts on sub-typing entities with RMs that would (as separate objects), have specific formatting  - such as VIN "numbers" or phone numbers (both of which are actually character strings)?  Is it better to have the single (if more generic), RM for the super-type, or separate more semantically expressive RMs for the subtypes? I tend to go with the more expressive conceptual approach, figuring that type validation can be done elsewhere.  Of course, the given UofD and requirements have to be considered.

    BRN..
