B737 DEP FROM LAS IS DIRECTED TO CLB WITH RESTRS BUT FAILS TO COMPLY WITH SUBSEQUENT ALT XING REQUIREMENT.

Narrative

WHILE DEPARTING LAS ON THE SHEAD SID; DEP CTL CLRED US TO 'MAINTAIN FL190 COMPLY WITH RESTR.' THE CAPT AND I HAD BOTH READ AND DISCUSSED THE READ BEFORE FLIES CONCERNING ALTDEVS ON LAS DEPS; SO WE LEFT THE ALT SELECT SET TO 7000 FT UNTIL XING ROPPR. THE ALT WAS THEN SET TO FL190 AND THE CLB CONTINUED. UPON XING TARRK; DP CTL ASKED FOR OUR ALT; WHICH WAS 16000 FT; AND THEN INFORMED US OF A XING RESTR OF 11000 FT AT TARRK. I FEEL 2 FACTORS CONTRIBUTED PRIMARILY TO THIS DEV: 1) ALTHOUGH WE BOTH READ AND WERE AWARE OF THE POSSIBILITY OF MISUNDERSTANDINGS; ALL THE ATTN HAS BEEN CTRED ON THE INITIAL 7000 FT RESTRS ON THESE DEPS WITH BARELY A PASSING MENTION OF OTHER RESTRS. SO NATURALLY OUR ATTN FOCUSED ON THE 7000 FT RESTR AND MISSED THE OTHER. 2) THIS TYPE OF PROC IS UNIQUE AND EVEN THE PHRASEOLOGY DIFFERS FROM THAT OF THE SIMILAR RNAV STARS. I HAVE NEVER SEEN OR FLOWN A SID WITH XING RESTRS LIKE THOSE ON THE SHEAD. WHEN CLRED TO DSND VIA A STAR; YOU ARE TOLD JUST THAT 'DSND VIA THE (SUCH AND SUCH) ARR.' WHILE ON THE DEP; WE ARE TOLD TO CLB TO THE FINAL ALT. THE BOTTOM-LINE IS THAT EVEN BEING AWARE OF POSSIBLE CONFUSION; WE BOTH MISSED THIS RESTR ON THE DEP CHART. CERTAINLY NEITHER OF US WILL MISINTERPRET THIS TYPE OF NOTATION; BUT OTHERS MAY FALL INTO THE SAME TRAP. PERHAPS AN ADVISORY CIRCULAR OR SIMILAR TYPE OF TRAINING DOCUMENT IS WARRANTED WHEN PROCS CHANGE APPRECIABLY LIKE THIS.
