[rules-users] MultiValueRestriction

[Iftikhar Khan]

Hi Wolfgang

My question was more about if the second way of writing was more preferred
because of some solid technical reason rather than just a matter of syntax;
that's how I interpreted the text as it makes the conditional statement
"but if you are testing for equality...".

Anyway thanks for confirming that there is no difference other than coding
style.

Regards

Iftikhar
