[j-nsp] policy subroutine evaluation: route characteristics

[Pekka Savola]

Hi,

Quite some time ago, I noticed and filed a doc bug on policy 
subrouting evaluation:

http://www.juniper.net/techpubs/software/junos/junos74/swconfig74-policy/html/policy-overview-framework17.html

in particular, it says,

"[...]. If one of the [subroutine] actions is meant to manipulate 
route characteristics, the characteristic is changed regardless of 
whether accept, reject, or neither action is specified."

At least my tests indicate that route characteristic manipulation is 
never done.

This seems worth discussing because both behaviours are desirable; in 
certain policies, we'd like to just get a TRUE/FALSE back (no 
manipulation), in most cases subroutines should act like real 
subroutines also allowing route manipulation.

Is the intention to fix the code to correspond to the doc, change the 
doc and remove this feature, or extend to allow both behaviours?
