The author changes the UUID each time the document is revised.
Subscriber B includes the UUID in the link to the style sheet, 
Subscriber A does not. Adding a version semantic to the URL helps URL
based caching but it doesn't help duplication of style sheets (I can't 
imaging many webmasters wanting external links to something as 
fundamental as their style sheets). Simple UUIDs allow style sheets to 
be replicated without interfering with the caching.
