Very sweet :) You could do the same kind of thing for decimal formats to use with format-number(). Of course the only slight drawback is that the document('') call will only get the current stylesheet document, and therefore won't search for keys defined in imported or included stylesheets (or indeed stylesheets in which this one is imported or included). Perhaps functions like key-available() and decimal-format-available() would be handy.
