Narrative:
Aircraft was told to turn right to 315 degree heading and to 'resume' the palace 2 SID. Filed routine was dtw direct dunks J70 bae. As our heading did not have us pointed at dunks intersection, I queried the controller as to what he meant by 'resume.' he responded with 'intercept J70.' our heading had us intercepting J70 east of dunks (we were headed wbound on our flight plan). I have asked for a clarification in the past as to what is intended by 'resume the palace 2,' and I have received 3 differing responses: 1) proceed direct dunks, 2) intercept dxo 296 degree radial to dunks, flight plan route, and 3) intercept svm 276 degree radial (J70) to dunks, flight plan route. This is very confusing. The good news is that most controllers at dtw don't issue this sort of clearance. They very clearly state 'cleared direct dunks, join the dxo 296 degree radial, or join J70...flight plan route.

Title: FLC OF A B757 ASKED DEP CTLR FOR CLRNC CLARIFICATION DUE TO THE CTLR'S PHRASEOLOGY USED AFTER A VECTOR HDG TO RESUME PUBLISHED SID.
Narrative: ACFT WAS TOLD TO TURN R TO 315 DEG HDG AND TO 'RESUME' THE PALACE 2 SID. FILED ROUTINE WAS DTW DIRECT DUNKS J70 BAE. AS OUR HDG DID NOT HAVE US POINTED AT DUNKS INTXN, I QUERIED THE CTLR AS TO WHAT HE MEANT BY 'RESUME.' HE RESPONDED WITH 'INTERCEPT J70.' OUR HDG HAD US INTERCEPTING J70 E OF DUNKS (WE WERE HEADED WBOUND ON OUR FLT PLAN). I HAVE ASKED FOR A CLARIFICATION IN THE PAST AS TO WHAT IS INTENDED BY 'RESUME THE PALACE 2,' AND I HAVE RECEIVED 3 DIFFERING RESPONSES: 1) PROCEED DIRECT DUNKS, 2) INTERCEPT DXO 296 DEG RADIAL TO DUNKS, FLT PLAN RTE, AND 3) INTERCEPT SVM 276 DEG RADIAL (J70) TO DUNKS, FLT PLAN RTE. THIS IS VERY CONFUSING. THE GOOD NEWS IS THAT MOST CTLRS AT DTW DON'T ISSUE THIS SORT OF CLRNC. THEY VERY CLRLY STATE 'CLRED DIRECT DUNKS, JOIN THE DXO 296 DEG RADIAL, OR JOIN J70...FLT PLAN RTE.
