Ok, I guess that could be a gotcha... in which case, just do:


It's funny how this has come up - I've just left a place where they
had two types of XML - one with <page> for the root element, the other
with <response>, and throughout the code, all over the place, they had
choose/when's with [ancestor::page] and [ancestor::response]... so I
changed it all to use global variables instead.  The gotcha didn't
occur to me at the time.... I think they will be alright though :)
