I sort of agree. I think that this is where XSL-FO will come in. XML
will first be transformed to device-independent layout, and then that
will be transformed to HTML/XHTML for the Web, WML for the mobile phone
(for now), PostScript for print, Director for CD-ROM publications, FDML
(Fridge Door Mark-up Language) for showing on the front of your fridge
and BOEML (Back Of Envelope Mark-up Language) for developing radical
ideas.

That way, if your XML source data changes you only change one XSLT
transform - to the FO. And adding a new device only involves saying how
a particular FO declaration works for that device. (Note that means only
once *ever*, not once per XML document or once per project. You only
need to say how FO instructions are rendered on that device once - we
could all share the same XSLT file.)

This would make a WAP gateway into a simple XSL-FO to WML mapping
server, and the rest of us wouldn't have to learn WML.

It also raises an issue which I'm quite into at the moment, that of
chaining transformations.
