    > What's the difference between . and data(.) please?
    
    . is the current item (most likely an element node in this case)
    data(.) is the typed value of that node.
    so if you are on an element node
    . instance of xs:boolean
    will be false as . is an element not a value, and in 
    particular not a boolean.
    but
    data(.) instance of xs:boolean
    will be true if the content of the element is schema typed 
    to be boolean.

What could you do with data(.) by itself then?
'A typed value' ????

Say the text() value of the context node came from an instance
whose schema said it was int.


Does it only make sense when used in conjunction with 'instance of' ?
  IIRC they've got rid of a group of functions that used to test if
X was int|real|date etc. Is this the replacement for those?
