It may not sound much, but I was certainly extremely impressed a
couple of years ago to so someone at one of the SGML/XML conferences
demonstrating how to use AFs with data representation. By a simply
manipulation, the same dataset could be rendered as a pie chart, line
graph, scatter plot, histogram ... While quite a few commercial
packages can do this inside their environment, it was interesting to
see this done in an 'open' manner, but especially interesting to see
it done in a way where the representation format could be determined
by the information content itself. Maybe I'm out on a limb here, but
the idea of 'intelligent data' like this (and XSLT has some of that
funtionality, albeit highly watered down) rather catches my
And for an honest attribute cry out ...
I might say 'element,' but the word is over-worn.
