DSP - Item Tag Processing - Rule Based Mapping - Expression operators

[RLANE]

What are the available expression operators that can be used in Rule Based Mapping? All of the examples use "=".
My immediate need is to know how to use "not euqls" as the operator, like the Javascript syntax "!=" or the SQL syntax "<>".
Why? I want to only execute the rule if the tag in the expresion is NOT blank.
