RE: [SCXML] <anchor> stuff?

Jim,
thanks for answer.

1.So, all types of anchors must be popped.
Not only the type of current anchor transition.

2.Or you mean that there is a stack for every anchor type.

If first is correct, what purpose of different types of anchors?
I thought that it's for partitioning of different parallel subtasks.
I mean no parallel substates, but different subtargets of machine destination.
