spetral rule set function for value is not equal to somethig

[jmgamboa]

I am trying to ensure the selected path is not certain value as opposed to exist within a given set of values

...
given: $.path.value
function: enumeration
then:
   field: @key 
   function: enumeration
   - instead of equal to this, not equal to this 

would i need to do a custom function for this?

Have you tried pattern function with notMatch config?
