Node features in a rule action

[GoogleCodeExporter]

Hi, could you implement using Node features in rules' action sequences?  It's 
not possible now but it would greatly improve user experience. For example I 
have a code:

feature nasal
feature flap
feature approximant
feature trill
feature sonorant (type=node children=nasal,flap,approximant,trill

If I want to change all syllabic sonorants to plain sonorants I'd like to be 
able to write [+sonorant +syllabic] => [+sonorant -syllabic]. Now I have to 
write this down for every child. I don't know if this is an issue or I'm doing 
something wrong, but I thought it would be best if I wrote it here.

Good news: this already exists! The only problem is that Node features don't 
use the binary notation (+/-), but the unary notation for "present/absent". 
What this means is your rule should have:

[sonorant +syllabic] => [-syllabic]

Which will do exactly what you requested above.
