Yet it can be done without any extensions. Try to apply the following stylesheet
to your <someroot> sample. The key idea is that document('') returns the root of
the stylesheet itself; in this way, you can address pieces of the stylesheet as
if they were elements in the source document.

However, I think it isn't a good idea to intersperse style with data. IMO, you
should better put your location data into a separate XML file, marking them with
normal markup instead of xsl:variables. Then you can access them using
document() function, in the same way that I used to extract these data from the
stylesheet.
