* <li> Some level 1 calls are not implemented because they will never be used
* by our connector infrastructure. Eventually, these will be documented as part
* of framework documentation. In this implementation, they also throw

* <li> Some level 1 calls are not currently needed by our implementation, but
* may be soon. These are marked with todos and throw UnsupportedOperation
