XML Problems

Either there are two problems with selecting XML, or I am seriously
misunderstanding something.

I am using protocol version 7.2

First, when I select from an xml column, SQLDescribeCol reports the sqltype
as SQL_CHAR instead of the expected SQL_SS_XML.

python          7FFF79F56180 EXIT  SQLDescribeCol with return code 0
(SQL_SUCCESS)
SQLHSTMT          0x7fc35a616080
 SQLUSMALLINT      1
SQLCHAR         * 0x7fff59073a30
  | s                                        |
 SQLSMALLINT       300
SQLSMALLINT     * 0x0
SQLSMALLINT     * 0x7fff59073a2e (SQL_CHAR)
 SQLULEN         * 0x7fff59073a20 (2147483647)
SQLSMALLINT     * 0x7fff59073a1e (0)
 SQLSMALLINT     * 0x7fff59073a1c (SQL_NULLABLE)

Second, SQLGetData always returns SQL_SUCCESS, even when the buffer is too
small. It NULL terminates at the given buffer length but gives no
indication more should be read.

Am I missing something?

Thanks,
