Hi,
it would be really useful if we could set the id element in sequence diagrams, so we can reference the specific elements from other diagrams for example.
@startuml
'reference other diagram
note over a_participant: look there [[other_diagram.svg#my_set_id]]
' or
foo -> bar: foobar [[]other_diagram.svg#foobar]
@enduml
In terms of syntax it could as follows, which enables setting more than one attribute, which might be useful if any post-processing is happening.
@startum
note over the_other {id=my_set_id}: note with a user specified id
foo -> bar {id=foobar}: Here we start foobar
@enduml
