"ref : Optional selector binding expression enabling submission of a 
portion of the instance data. The selected node, and all descendants, 
are selected for submission."

also (11.1 The xforms-submit Event):

"A node from the instance data is selected, based on the attribute ref 
on element submission. This node and all relevant child nodes are 
considered for the remainder of the submit process."

So the root node will be the node referenced by the XPath expression in 

In your specific case (<submission ref="/a/b/c" .../>), the submission 
would be



Yes, you should use the instance('id') function:
<submission ref="instance('id') .../>"
