  I think you are confused:

         ret = xmlSchemaVCheckCVCSimpleType(ACTXT_CAST pctxt, node,
                     type, value, val, 1, 1, 0);

in C parameters are separated by comma, there is only 8 parameters, 
ACTXT_CAST is a macro (as the all upercase convention indicates)
which does a cast of the first parameter.
