-ICreateLayer, which all(?) drivers implement, have geometry type as an argument. The method should call CPLError() with CPLE_NotSupported and return NULL if the driver does not support measures. Similarly for ICreateFeature and ISetFeature.
+ICreateLayer, which all drivers that have create layer capability implement, have geometry type as an argument. The method should call CPLError() with CPLE_NotSupported and return NULL if the driver does not support measures. Similarly for ICreateFeature and ISetFeature.
+
+There is a question whether the user-oriented API functions (CreateLayer, CreateFeature, and ISetFeature) should (silently) strip out the measures before continuing to the I* methods. This (side effect) may not be what is wanted in some usage scenarios but it would follow the pattern of what is already done with non linear geometries.
