    17 <context><p>A derived UI Data MTM is simpler to implement than the MTM classes,

    18 and most of its code is specific to the protocol that is being implemented.

    19 The UI Data MTM implementation can require a resource file that details the

    20 strings used by the MTM and a list of functions (as command IDs) and flags

    21 that are specific to the MTM. </p> </context>
