SQLXML bulkload - parent-child relationship and autogeneration of IDs.  IDs not inherited.

I am trying to get a bulk-load statement to work using SQLXML.

I can insert the rows into the parent table fine, and the DB generates a value for the PK coulmn (using the Default).

I cannot get the child rows to be inserted because the FK column can't be null.  MS say this is by design (great) and provide no solution.

My tables have a constraint (FK) between them.

My source XML contains no ID.



However, an alternative I have done is to edit the XMl at runtime and insert a new node to make an ID for each parent.
The problem still exists, and it crashing saying that it cannot find a source for the child's FK column.

 
What I really want is for it to throw the parent data at the DB and have an ID auto-generated (using the DEFAULT) for the parent ID, and then have this propgate down to be the FK for the children.  However SQLXML is unable to do this (microsoft document this), but it is (apparently) able to propogate the FK down if the parent's ID is provided in the source data.  I'm trying this approach but it's failing.


Please advise
