I have a condition:

<if-src-attr mode="nocase" name="DeferredAdd"

DeferredAdd can be an MV list.

I know that if I test is A = B, where either (Is that true) is a multi
valued attribute then it will return true if ANY of the values are the same.

What about the not-equal test?

If DeferredAdd contains
as values and I test that it is not equal to APPX what will the test
return? True or false? I would want it to return false, since it is
equal to ONE of the values.
