(cf. Expert):<br>
<br>
"Each rule has a salience attribute that can be assigned an
integer <i><b>number</b></i>,"<br>
<br>
This does not event remotely indicate that you can use an <i><b>expression</b></i>
involving bound variables.<br>
<br>
If it isn't documented, nobody will use it. Being in front of
the when part where the bindings occur, it is
counter-intuitive to other bound variable references, and so I
didn't even try.<br>
<br>
However: good to know, and thanks!<br>

I'll give write permission to docs to anyone that wants to assist :)<br>
<br>
Wolfgang you already have write permissions I believe? :)<br>
<br>
I would recommend xmlmind as the authoring tool.<br>
