 * NSSPKIXAttribute_Create
 *
 * This routine creates an NSSPKIXAttribute from specified components.
 * This routine may return NULL upon error, in which case it will have
 * created an error stack.  If the optional arena argument is non-NULL,
 * that arena will be used for the required memory.  There must be at
 * least one attribute value specified.  The final argument must be
 * NULL, to indicate the end of the set of attribute values.
 *
 * The error may be one of the following values:
 *  NSS_ERROR_NO_MEMORY
 *  NSS_ERROR_INVALID_ARENA
 *  NSS_ERROR_INVALID_OID
 *  NSS_ERROR_INVALID_ITEM
 *  NSS_ERROR_INSUFFICIENT_VALUES
 *  NSS_ERROR_VALUE_OUT_OF_RANGE
 *
 * Return value:
 *  A valid pointer to an NSSPKIXAttribute upon success
 *  NULL upon failure.
