I use 13,14 and 15 as only internal PostGIS number availables,
Standards values:
ISO SQL/MM draft 2009 (5.1.58 p178):
POLYEHDRALSURFACE 15
TIN: 16
TRIANGLE 17
POLYHEDRALSURFACEZ: 1015
TINZ: 1016
TRIANGLEZ: 1017
POLYHEDRALSURFACEM: 2015
TINM: 2016
TRIANGLEM: 2017
POLYHEDRALSURFACEZM 3015
TINZM 3016
TRIANGLEZM 3017
It's also consistent with OGC SFS 1.2 (06-103r3)
8.2.8 p67
