ODABAClient :: Exist - Check database path

The function checks, whether the path refers to a valid database position. The function only checks for valid ODABA databases. Files which are not recognized as such are ignored. Thus, the function does not allow checking the existence of an xml database.

The path name may contain symbolic names, which are resolved before checking the path. When running on a server the request is passed to the server, i.e. symbolic names must be known at the server side.
