Xap does replicate some of Dojo's functionality simply because any
UI/event description has to do a few things; however, it's intended to
be a wrapper and extender for _anybody_'s widget system...at the very
least, this allows you to keep a page description which is
vendor-neutral, giving you more freedom to change later on.
Consider: what if you want to adapt a dhtml-based page for a
voice-server? After you find equivalents for what UI pieces you can
(text-to-speech for outputted text, voice prompts for fields,
recognisers for "OK" and "Cancel" buttons,...) you could keep the same
.XAL and replace components one-by-one, something even Cocoon can't do.
Xap also makes it relatively simple to add, delete, or replace elements
in your U.I. after loading---large pieces of interface can be predefined
and loaded in as needed in response to triggered events.
Xap will give you macros, and more importantly (IMarrogantO) a namespace
for managing objects ("mco"s); a single mco can point to complicated
pieces of code, allowing for better modularity in describing what you
applications do.
I hope that this has been of use; someone else jump in to fill in the
(probably large) chunks I've left out, and correct anything I've got
wrong....

Cheers guys,
i am playing with ajax at the moment and try out dojo. i was curious why
i should use XAP some time? Meaning, it seams you are building a kind of
scripting language (like XUL) based on dojo. Why are you not simply
using dojo? What will be the advances?
When i have this xap script, is this also a templating engine? I am
using tiles at the moment, can i think about xap as a replacement for
tiles? or is it an extension?
Sorry for my dump questions, maybe you could enlighten me a bit :-)
Cheers,
Chris
