Schema Group Order type - Sequence, choice and all

In the schema editor in a BizTalk project. One of the paramaters for a node is the group order type. Your choices are "Sequence", "Choice" or all.

The sequence requires that the records be for example taged records:

(This is for my example)

40

41

41

42

49

80

Or any sequence re enter

So you could have:

40

41

41

42

42

42

80

Depending on how you set your minimum's and maximum's

For "sequence" This would fail:

40

41

41

49

41

80

If you change to "choice" it would work.
