Drupal Association members fund grants that make connections all over the world.
The API.txt states:
If the token is intended to generate a path expected to contain slashes,
the token name must end in 'path', 'path-raw' or 'alias'. This indicates to
Pathauto that the slashes should not be removed from the replacement value.
However, it doesn't work for 'path-raw'. I had to switch to simply using 'path'.
