I did see your initial post and I'm sure everyone of us could shave a few
bytes of data transmitted.

Trouble is, until there is a 'Real World Standard' e.g. the W3C Standard for
an Order we aren't going to get very far IMHO, XML or JSON (or OKI KOKI
2000)

Naive I know!

Did you see my initial post?

JSON:

[ "customerid" : 1123454, "name" : "Joe Pluta", "email" : 
"junkmail@xxxxxxxxxxxxxxxxx" ]


*By itself*, the *raw* XML is nearly the same:

<customer customerid = 1123454 name = "Joe Pluta" 
email="junkmail@xxxxxxxxxxxxxxxxx" />


But this assumes that you use attributes rather than children.  Many people
don't and children fatten XML considerably:

 <customer>
   <customerid>1123454</customerid>
   <name>Joe Pluta</name>
   <email>junkmail@xxxxxxxxxxxxxxxxx</email>
 </customer>


That's almost a 50% increase, I think.  But then go to a standard web 
service using SOAP, and you're talking about typically at least 300 
characters of SOAP envelope, which would more than quadruple the size of 
the original message.
