I think this is a potentially very powerful technique as it allows one to
take
a further declarative 'step backwards', and define the desired output for
a transformation without having to define the steps to get there, or indeed
the location of the stylesheets.

I think a TRaX based trial implementation for this should be fairly simple
to
implement (although obviously you'd want to limit the search depth that
your engine uses).

Also, granted multiple piped transforms will likely be sub-optimal compared
to a single specialised transform. But I think experience has shown that
pipes are very useful constructs.

Cheers,

L.
