I think the default medium should be "screen" and then the DSSL Online
flow objects (scroll, link etc.) should be assumed. The SGML
transformation you are referring to is non-standard Jade extensions
(indeed they are useful) and using them by default is therefore not a good
idea.

I don't see why one should specify that RTF should be used for formatting
the document. In my opinion, the process of formatting is implementation
dependent and will vary between different browsers. What I am trying to
say is that if one has a native DSSSL browser, it would be very
inefficient to do the formatting via RTF.

Is this different from the XML standard?
