Collects interoperability issues that we are currently aware of, and that may need resolution sooner or later. Is not intended to be complete.
- CardSpace "card format" issues:
- should the card format be maintained by a proper standards body? Or should Microsoft maintain its version, and Higgins another? (with Higgins's being a proper superset, for example?)
- what are the extensibility points of that format? Does CardSpace tolerate elements in the file that it does not understand?
- The above includes the circumstances under which Higgins cards can be exported and imported into Microsoft CardSpace.
