       But if you have a stable URL to a revision of the versioned
       resource, then I would assume it is good 'for all time' -- since
       the namespace of the stable URL is effectively outside that of the
       dynamic URLs.
    
       I still don't understand all the characteristics of a stable URL --
       or what it represents.
    
    The definition of a stable URL has undergone some mutation, so some
    confusion here is understandable.  Currently, it just means a URL that
    identifies a particular revision (it is unaffected by Target-Selector
    or Workspace headers).
    
    We used to have a stronger definition (i.e. the URL was guaranteed
    to always identify that revision), but there were complaints that
    this was too hard for some servers to implement, so we weakened it.
    
    So now a server can play URL games and just extend the name of the
    versioned resource in funny ways, e.g. the stable URL for rev23 of
    versioned resource "/a/b/c.html" could be "/a/b/c.html;rev23".
    
    Cheers,
