That's a mistake if it is :-(   .  Hopefully P will jump in here with
some advice....:-)

In reality the message will actually still go out OK as xAP sent
messages don't go via a hub, however it may be dropped by your hub
(servicing its listeners) as strictly it is non compliant.  This would
mean that any xAP applications listening via the hub wouldn't see it.
Which hub are you running (or application running as a hub) ? - I think
in Viewer and Hub GUI you can set an option to still pass malformed
messages - I am just a bit unsure whether it truly passes these messages
or whether it just displays them (and still drops them).  I also know
that Patricks' hub does very little error checking and hence would pass
these types of messages OK, if you wish to download that.

There is also another possible 'kludge' to get around this - if you can
choose the source name then try calling it something like

Rocket.Bridge.One:kludge   ( note the :  )

This will effectively give it a sub address and hence the 01 at the end of
the UID would be acceptable.  (technically that is a really awful kludge
but there you go...)
