446 - header is XDB_header type
447 - pxdbed flag is set to 0
449 NOTE: the pxdbed flag is meaningful also in the not
450 already pxdb processed version of the header,
451 because in case on non-already processed by pxdb files
452 that same bit in the header would be always zero.
453 Why? Because the bit is the leftmost bit of a word
454 which contains a 'length' which is always a positive value
455 so that bit is never set to 1 (otherwise it would be negative)
457 Given the above, we have two choices : either we ignore the
458 size of the header itself and just look at the pxdbed field,
459 or we check the size and then we (for safety and paranoia related
460 issues) check the bit.
461 The first solution is used by DDE, the second by PXDB itself.
462 I am using the second one here, because I already wrote it,
463 and it is the end of a long day.
464 Also, using the first approach would still involve size issues

4657 * find our way to the SOM record describing the type, switch on
