| + | ===== The <compoundCondition> Element ===== | ||
| + | ==== Definition and Usage ==== | ||
| + | |||
| + | The [[compoundcondition|<compoundCondition>]] element defines a logical expression among its | ||
| + | child elements by means of its Boolean //operator// attribute. | ||
| + | |||
| + | A //delay// attribute may also be defined specifying that the compound | ||
| + | condition is true after a time delay from the expression relating its child | ||
| + | elements is true. | ||
| + | |||
| + | When an "and" compound condition relates more than one trigger condition | ||
| + | (that is, a condition that is satisfied in an infinitesimal time | ||
| + | instant–--as for example, the end of an object presentation), the compound | ||
| + | condition shall be considered true in the instant immediately after all the | ||
| + | trigger conditions are satisfied. | ||
| + | |||
