I have the following code:
@startuml
package "Level0" as l0 {
package "Level11" as l11 {
[test4]
}
package "Level12" as l12 {
class Level3 as l3 {
hello
}
}
}
@enduml
The code doesn't compile, and the error is rather cryptic, the compiler complains about:
"class Level3 as l3 {"
What's wrong with this diagram? I have seen package diagrams with classes inside.
