Using the debugger, the following Id field was not being set:

MOVE oXref TO oref.ns1:Header.ns2:Field;
CREATE NEXTSIBLING OF oXref NAMESPACE ns1 NAME 'Id';

SET oref.ns1:Header.ns1:Id = iref.ns1:Id;

The weird thing is if I add VALUE '' to the CREATE command above, it works.

Anyone know why this would fix it?

Thanks!

Code:
SET oref.ns1:Header.ns1:Id = iref.ns1:Id;
Will set the oref.ns1:Header.ns1:Id to Null if the source iref.ns1:Id is null.
This will effectively remove the ns1.Id tag from your output.
Code:
SET oref.ns1:Header.ns1:Id VALUE = iref.ns1:Id;

This will keep the tag in case the source is null and assign the null value to the tag. Enjoy

As an add on to what F.J. said, examine the result of "set oref.ns1:Header.ns1:Id = 'foo';".
