[postgis-devel] OGIS curve and surface geometry types?

1. Are the OGIS curve and surface geometry types supported under PostGIS?
I didn't see them listed in section 4.2.2 of the user's guide, but wanted to
make sure. They are defined in the OGIS OleDbGis.h header file.
2. Where are the POINTM, LINESTRINGM, POLYGONM, MULTPOINTM,
MULTILINESTRINGM, MULTIPOLYGONM, GEOMETRYCOLLECTIONM types coming from? The
OGIS OleDbGis.h header doesn't list these types. Is there an inconsistency
between the two OGIS specifications?
3. Is MULTPOINT, and MULTPOINTM a typo in section 4.2.2 of the users guide?
Should it be MULTIPOINT and MULTIPOINTM instead?
For reference the OleDBGis.h heaer file contains the following OGIS_GEOMETRY
DBGEOM_GEOMETRY = 0x1L,
DBGEOM_POINT = 0x2L,
DBGEOM_CURVE = 0x3L,
DBGEOM_LINESTRING = 0x4L,
DBGEOM_SURFACE = 0x5L,
DBGEOM_POLYGON = 0x6L,
DBGEOM_COLLECTION = 0x7L,
DBGEOM_MULTISURFACE = 0xB,
DBGEOM_MULTIPOLYGON = 0xC,
DBGEOM_MULTICURVE = 0x9L,
DBGEOM_MULTILINESTRING = 0xA,
DBGEOM_MULTIPOINT = 0x8L
Thanks for the help.
