On a Drupal site, when setting up pathauto for nodes, sometimes it is useful to have the full nested path of parent terms of the channel (or primary vocabulary) for the article in the url alias to give the impression of a directory structure to the taxonomy vocabulary. This will allow users to see urls to nodes like domain/term1/term2/term3/node-title-or-whatever where term3 is the channel under which the article is published.
