[rules-users] User and/or Code problem with insert/retract and salience

[Wolfgang Laun]

Probably you have checked this, but just to make sure:
If you omit rule "a1": does fact A2 fire with rule "a2" at salience 65?

What does "...rules are like the following..." mean? I guess they are
not identical, that would be pointless. So, in which way do they differ?
