Narrative:

On soldo 2 RNAV departure; aircraft began turn from mechl to mavvs before reaching mechl. Because mechl is not a compulsory flyover point; aircraft will lead turn this point to stay in the depicted track. Controller was alarmed because aircraft did not overfly mechl but during subsequent conversation with controller; was advised that departure expects aircraft to overfly mechl on soldo 2. Suggest that mechl be changed to a compulsory flyover point if indeed departure expects overflt of this point. Controller also advised there was no danger of aircraft separation in this incident.
