<DIV><FONT face="Arial" size="2">When I
first looked at XAP a few months back my initial though that for the most
part XAP was a document (message) exchange definition and it would seem
that use of XML would be more mainstream and flexible.&nbsp; I like the
idea of using XML.</FONT></DIV>

<DIV><FONT face="Arial"><FONT
size="2">Does&nbsp;the proposal that is being foreshadowed
change the&nbsp;header/body structure of an XAP message or is it one
where tools are being introduced&nbsp; so an XAP
node&nbsp;can&nbsp;translate between XAP schema using&nbsp;XML
technologies?<SPAN class="532415217-17032004"><FONT

class="532415217-17032004"><FONT
color="#0000ff">No absolutely not - the message structure on
the wire stays exactly the same. The decision not to use&nbsp;XML on
the wire was a conscious one -&nbsp;if you look at the last example you
can see why - it's hopelessly inefficient in byte terms, and much much more
complex than xAP&nbsp;to parse. As you suggest, the similarities
allow&nbsp;programmatic mapping from xml to xap structures and
vice-versa - exposing this to programmers would allow them the benefit of
xml tools on those machines powerful enough to exploit them,
but&nbsp;still allow low end devices to come to the
party.</FONT></SPAN></FONT></FONT></DIV>
