Is there a way to create overlapping / independent groups in sequence diagrams?
group (1) over A, B : My first group
A -> B: A to B message
group (2) over B, C : My second group
B -> C: B to C message
B -> A: B to A message
end group (1)
C -> B: C to B message
end group (2)
Currently, the group names beyond 'end' tags are not considered.
