31 normal services have none of them - they can be fed directly into the "play"-handler.
32 normal directories have both of them set - you cannot play a directory directly and the UI should descent into it.
33 playlists have "mustDescent", but not "isDirectory" - you don't want the user to browse inside the playlist (unless he really wants)
34 services with sub-services have none of them, instead the have the "canDecsent" flag (as all of the above)

156 SWIG_VOID(real_returntype_t) hides a return value from swig. This is used for
157 the "superflouus" RESULT return values.
159 Python code has to check the returned pointer against 0. This works,
160 as all functions returning instances in smartpointers AND having a
161 RESULT have to BOTH return non-zero AND set the pointer to zero.
163 Python code thus can't check for the reason, but the reason isn't
164 user-servicable anyway. If you want to return a real reason which
165 goes beyong "it just doesn't work", use extra variables for this,
168 Hide the result only if there is another way to check for failure! */
