 The transformation below copies to the local file system (to the
"CongressVotes" subdirectory of the directory that contains the
stylesheet module)  *all* votes from 1 to 500 of sessions 1 and 2 of
congresses 111 and 112.

I got:

Congress 111, Session 1, votes: 396, lowest 1, highest 397

Congress 111, Session 2, votes: 297, lowest 2, highest 297

Congress 112, Session 1, votes: 234, lowest 2, highest 235

Congress 112, Session 2, votes: 249, lowest 2, highest 251


Here is the transformation:
