My opinion: if a form author specifies @origin, then that should be the 
source of the nodes to copy. If empty, then nothing is copied.

We should *not* revert to using the last node of the node-set binding. 
This would be really surprising to me as a form author.

The text says it can either:

1. Not be specified at all. This is possible because @nodeset and @bind 
are now optional on xforms:insert.

2. Be specified and return an empty node-set.
