  Yes.  But Michael did it better than me :-)

  And as Michael said, in this case, you can directly cut what you want
in the document-uri.

  Intresting.  I'm used to use document trees in variables to simulate
randomly-accessed tables, indexed by strings for example.  But here,
because the "index" (the thing to use as such) is a document node, I
didn't see how to don't use a choose.  It's not really the same thing,
but it looks clearer and more compact than the choose.
