I've looked at quite a few of the xPL implementations available for
linux/unix machines and none of them would support it.  That seems to me
like a good indication that it isn't intended.

It would be a good idea to clarify this in the document.

There are other similar issues that would probably benefit from some
clarification.  For instance, whether developers should be permitted
to repeated field names - currently there aren't any restrictions on
developer fields.

For example:

x10.basic
{
command=on
device=b2
command=off
}

I suspect some implementations might treat this as 'command=off' even
though 'command=on' field is in the correct position.

It would probably be a good idea to specify that:

Field names in the body should not be repeated.  Implementations
should use the first value and ignore subsequent values if they
receive messages with duplicate fields.
