- * selector.\r
- *\r
- * The 'funcs' field is used for application\r
- * specific functions.\r
- *\r
- * For COMPAT types the funcs field gives a\r
- * set of functions that handle this type, this\r
- * supports the old d2i, i2d convention.\r
- *\r
- * The EXTERN type uses a new style d2i/i2d.\r
- * The new style should be used where possible\r

- * MSTRING is a multiple string type, it is used\r
- * for a CHOICE of character strings where the\r
- * actual strings all occupy an ASN1_STRING\r
- * structure. In this case the 'utype' field\r
- * has a special meaning, it is used as a mask\r
- * of acceptable types using the B_ASN1 constants.\r

- * NDEF_SEQUENCE is the same as SEQUENCE except\r
