Yes, that's exactly my point. We need some kind of system (that isn't too
comlicated) that allows us to anotate data, and have it either processed or
displayed. I'm sure if people just added some proprietary extensions to
XHTML, took away some of the junk, and mixed in a few other languages (XLink
and RDF) then you would have the basis for an architecturally sound, well
processable "language".

This is the next major step towards a brighter Web (dare I say the Semantic
Web). Someone needs to create a "Mosaic for the SW", and they have to do it
fairly soon. We need something like the very original NEXT browser that
TimBL created: somthing that allows you to read and write to the Web in a
WYSIWYG environment without needing to see the source code or URIs. Also,
that "browser/editor" is going to settle on some type of output, and I think
it will be something similar to the annotated data in XHTML thing I am
talking about. Amaya already is 1% of the way there, but people need to move
it on the next 99%...
It would also be compatable with the Web of trust, and of only partly
recognizable languages, becuas it should be able to work out most
statements, but for the main part you would have the basic structural
framework (using some XHTML tags) and then have the data annotated with
XLink, RDF and so on. Bringing all of these things together is one of the
hardest things, but like I say, Amaya is getting there. Also IE5 can display
plain XML with CSS, so if some group of people developed some of these
principles and brought them al in line, there is no stopping them creating
the "Mosaic of the SW".

Of course, people must first settle onto the act that docuents and data are
inseperable, and that was the original purpose of the first message, and
this one moves me onto the next level (and hence this question): is anyone
developing an WYSIWYG annotation GUI?
