   RE: [xml-dev] ANN: new markup language for user interfaces

[ Lists Home | Date Index | Thread Index ]

Thank you Mike. I was having the same thoughts. The XALT idea is
technologically interesting. I'm trying hard to visualize some use-cases (or
areas where the XALT model does things better over existing solutions) but
am having trouble with it.

I can imagine uses in applications where *really* dynamic interface layouts
are needed (i.e. XSLT generated live dialogs based on some data or user
input). The only area I can think this might be handy is in creating
internationalized dialog boxes, where the entire layout of the screen might
change based on the language selection. That sort of thing.

Some other uses might be to map the XALT language into a general purpose UI
like HTML or WML (but then you start suffering from LCD issues), or perhaps
as a 'resource' description language that is baked into an application (much
the way it's done on Windows or Mac), or even mapping the XALT language to
low-level Windows or Mac resources as a sort of cross-platform UI resource
description language. I don't know. I'm reaching here. Besides it starts
stepping into XUL territory.

The way they have it now, tied into Swing and requiring the 'sandbox' etc,
I'm having trouble seeing the uses. Please don't get me wrong. I think it's
pretty high on the cool factor. Perhaps the author(s) would care to shed
some light.

Just my $0.02.
