[rules-users] Using constant for salience instead of hardcoded values?

[Wolfgang Laun]

You can use:

   - a fully qualified public static field, e.g. salience (
   (int)java.lang.Math.PI )
   - a DRL-defined function, e.g. function int FOO(){ return 10; } ...
   salience( FOO() )
   - a global, e.g. global Integer foo; ... salience ( foo ). But
   initialisation is clumsy and not checked by a compiler.
   - any field from any fact.

You can NOT use a static field imported with a "start" pathname, e.g.,
import function com.acme.*.

It have a sence when you have many rules and only several salience level.
They maybe more descriptive like START, VALIDATION, etc and easier to
maintain in the future. If it not possible right now, then maybe it worth to
request like feature request in the future?
