Actually the strategy from XProc I mentioned in my last message  
specifically covers XPath 1.0, NOT XPath 2.0. So it would be a good  
fit for XForms 1.1.

To make it clearer: XProc says that the context is set to an empty  
document node. This is not the same as saying it is an empty sequence  
or an empty node-set: it is a node-set containing a single node, which  
is a document node without children.
