交互⽚段(Interaction Fragment)：⼀个复杂的顺序图可以划分为⼏个⼩块，每⼀个⼩块称为⼀个交互⽚段，由⼀个⼤⽅框包围。常⽤的操作符包括：1) alt:多条路径，条件为真时执⾏。2) opt:任选，仅当条件为真时执⾏。3) par:并⾏，每⼀⽚段都并发执⾏。4) loop:循环，⽚段...
Use the Loop fragment for a basic repeating interaction. Use the Optional fragment for steps that are only performed if a certain condition is met. Use the Alternative fragment shape for an if-then or if-then-else process or interaction. The fragment comes with two sections, which ...
