I want to improve layout of my class diagram with the "together" keyword, but it does not group classes. If I use fully qualified class names (which should create namespaces according to the documentation), like in the following "puml" file, then "together" does not group classes visually.
@startuml
class p.A
together {
class p.B
class p.C
class p.D
}
class p.E
class p.F
@enduml
If I use class names without packages, like in the following file, B, C, and D are clearly grouped.
@startuml
class A
together {
class B
class C
class D
}
class E
class F
@enduml
