      <p>The sdtc:precondition2 extension allows a more flexible set of skip conditions on a set of criteria. Without this extension the skip condition is restricted to all criteria true. The extension allows a choice of the following logical operation extensions sdtc:allTrue, sdtc:allFalse, sdtc:atLeastOneTrue, sdtc:atLeastOneFalse, sdtc:onlyOneFalse, and sdtc:onlyOneTrue to be placed upon the encapsulated criteria or a criterion. The logical operation extensions nest a [0 .. *] sdtc:precondition2 extension allowing for a complex specification of nested skip conditions if needed.</p>

All AND criteria must be true.
If OR and AND criteria occur together, one criterion out of the OR-group must be true and all AND criteria must be true also.
If XOR criteria occur together with OR and AND criteria, exactly one of the XOR criteria must be true, and at least one of the OR criteria and all AND criteria must be true.
In other words, the sets of AND, OR, and XOR criteria are in turn combined by a logical AND operator (all AND criteria and at least one OR criterion and exactly one XOR criterion)."/>
