    So would this be, for example, a default aural XSL sheet that would take
XFO as input and transform into something to be aurally rendered? If so, I
like it :-)

    This would be accomplished by a client side transformation pipeline.

    I'm completely missing something about this XFO vs CSS debate for aural
rendering. If there exists the argument that:

    XML -> (xslt - server side) -> XHTML + CSS allows better client side
aural rendering than XML -> XSL (server side) -> XFO, then given the proper
XFO generation can;t we just:

    XML -> (xslt) -> XFO -> (xslt) -> XHTML + CSS (???) and get the exact
same aural rendering, assuming that the XML -> XFO xslt doesn't terribly
degrade the XML semantics. Since aural rendering in general will depend on a
reasonable: XML -> XHTML+CSS transformation, what is the difference if there
is an intermediate step which contains XFO? If I can't do an XFO ->
XHTML+CSS transformation it seems that there wound be something badly wrong
with XFO. And if this transformation can be done, then what is the argument

    What am I missing?
