You don't need to edit the XML manually.

Just right-click on your server name, hit Properties, then on the General
tab,
make sure the "Continue processing after first match" option is
ticked.
Click OK.
Not sure if you need to restart xPLHal - you shouldn't have to.

No problem with () - the only special case is for curly brackets {}.

Basically anything contained within {} will be checked by the determinator
engine, as follows:
SYS::TIMESTAMP will be replaced by the current date/time, in the form
yyyymmddhhmmss. This is useful for generating a unique number or timestamp.
SYS::DATE will be replaced by dd/mm/yyyy (current date)
SYS::TIME will be replaced by hh:mm:ss (current time in 24-hour clock)
Any global name will be replaced by it's actual value, e.g.
{WINDSPEED} will be replaced by the value of the WINDSPEED variable.

I don't think you can pull values out of the source message at the moment.
This was certainly on the list... but I'm not sure if it ever got actioned.

The idea was that something like:
{XPL::DEVICE} would be replaced by the "device" parameter from
the incoming
message.
But there are issues where more than one "device" parameter
exists in the
message.

As I think the ability to de-reference source parameters is pretty
essential for
this sort of thing, I'll move this to the top of my ToDo list.
