But not all clients are browsers and not all representations are HTML
or XML.  As the basis of a discovery mechanism for scripting clients
and the like, I have found it to be ideal.  Perhaps there isn't a big
need to implement this in browers (TBH that's not for me to say), but
as far as I'm concerned the spec still does have value.  The
alternative is for me just to make up a header syntax of my own -
easily done but wasteful in the long run.  Even the discipline of
turning relationship identifiers into URIs has been of value,
resulting in an self-describing system that is completely transparent
and client-independent.
