Create a empty adoc. Add a mermaid section. Declare a zenuml schema.
Here is what i got with asciidoctor extension (with also a simple other kind of mermaid schema to proof it work in other cases)

Here is what i got from another extension that manage mermaid code in md files

Look among the logs there for errors.

ZenUML requires an additional library which is not included. I guess that's the reason why it's not working:

Yes i'm aware of that. Some VS Extensions manage to render such schema. So it would be nice if this one could do it as well to render both ascci doc and included mermaid schema.
