One of my pet peeves is the Quantum Boolean anti-pattern.
'What the heck is that?' I hear you cry!
Well it is where some bright spark defines an element or attribute as boolean (true or false) but it may or may not be present (minOccurs="0").
What then happens is that you never get to see false. Either the element or attribute is present and set to true or it is absent and you have to guess that it is implicitly false.
Please decide to set it to boolean and make it mandatory or make it an optional marker element with no sub-elements or attributes.
