/* The XMLDB has a handle to keep connected state. To users of the API it is
* a void* but it may have structure within a specific plugin.
* The handle is independent from clicon so that (in principle) the datastore
* can work in other contexts than clicon.
* The connect API call sets the handle and disconnect resets it. In principle
* there can be several handles at one time.
