Some more feedback on loading SDTS DEM with GDAL.

My previous code which used an old version of "libsdts++" did the following,
to get the datum out of a SDTS DEM:

sb_ExtSpatialRef *pXREF;
pXREF = new sb_ExtSpatialRef(record);
// Find Datum type...
const char * strDatum = pXREF->getHorizDatum().c_str();
if (!strcmp(strDatum, "NAS") )
m_Datum = NAD27;
else if (!strcmp(strDatum, "WGC") )
[....]

When i now use GDALOpen() and GetProjectionRef(), i get a string:

"+proj=utm +zone=10 +ellps=clrk66 "

.. which doesn't contain the datum. Shouldn't it be contained in this
string?
