description: 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.
