Do analysis expressions have anything like an exclusive OR operator (e.g. "a xor b") or does it have to be done in the long-winded way "(a and not(b)) or (b and not(a))"? ("xor" is not valid syntax BTW).
There is no PE to achieve XOR directly in AF analysis. You can achieve using similar (a and not(b)) or (b and not(a)) syntax defined as part of your question.
As Lal mentioned there is no exclusive OR in Asset Analytics. You can find the expression references here:
