MAXIMUM STACK DEPTH

According to this old blog http://blogs.technet.com/b/engauged/archive/2005/11/08/413947.aspx the maximum stack depth is 30. When the stack is full, any new value pushed onto the top causes the bottom value to be removed and discarded.

CLEARING THE STACK

The stack is cleared at the beginning of each gauge cycle, or by applying the Clear Stack XML operator, "c". Of course, also during a panel Load/Reload.

DIFFERENT STACKS

The stack is shared between <Update> and all of the <Element> set. As well, each <Area>, <On Event> and <On Key> structures hold their own stacks.
