Mixing standard and convenience operations
You can mix standard and convenience operations without any problem. Note that the set of URLs used by standard operations (NGSI10 and NGSI9) and the set of URLs used by convenience operations (NGSI10 and NGSI9) are orthogonal.
However, take into account some convenience operations don't allow to specify any type for entities nor for attributes, so the rules described in using empty types section apply.
