I guess if the only tool you have is a hammer, everything looks like a nail.... For mission critical applications, realtime constraints and data redundancy are generally required. This to me implies higher level protocols than those codified in the data. XML doesn't solve this problem, and shouldn't pretend to. Let's take Bill's example to the limit, and say that the obboard computer sent out: <ACCIDENT> <VEHICLE>sd;ghligk;db/lflgniupg nbpppv</VEHICLE> <LATITUDE>klnsfvouvjisbdfubfibdbufubufbf/LATITUDE> <`340-968gn]0984588y873**(&&E$*(&& m8qf9hnc </ACCIcore dumped, your fault! would you still expect it to work? What about if it sends out the wrong vehicle identification, and the wrong positional data? Suddenly you have an ER team rushing out to the wrong place, looking for the wrong person. For the situation Bill outlined, I would expect a simple radio transmitter to work far more effectively: you can use triangulation to locate the source, and encode the radio signals to include a great deal of data redundancy in a much smaller number of bits. This is not to say that I don't sympathise with some of Bill's concerns. To me, a more valuable example is that of pressing the cancel button while downloading a document.
