This is the way XBRL works - the 'item' head is defined in the generic XBRL
instance Schema document, and members of the item substitution group
(representing actual financial facts) are defined in the Taxonomy Schema.
An <import> of the instance Schema in the Taxonomy Schema does the trick...
or is there something more subtle about your scenario concerning type
derivation that I'm missing?
