Have you noticed that vartype and type have different behaviors:
With ActiveX, when checking for the existance of a 'node', VARTYPE will error out:
?VARTYPE(foo.nodes(somekey).key)="C", will push an object refence error, while:
?TYPE('foo.nodes(somekey).key')="C", will return a true or false depending on the existance of the key!

Don't know if this has an revelance to your thread, but it is an interesting comparison.
