A microcall is an XML-dialect used to communicate
between a client and a server in a standard and
easy-to-use way. The client part is (usually)
implemented in Java and consists of a simple POJO
that can understand the XML messages returned by
the server response to a given call. The server
part is only responsible for returning standard
and correct messages in response to a given call.
The server usually does a lot of work when it
receives a call, but from the client standpoint,
the server only returns a message explaining the
result of the call.
