Mermaid: `classDiagram` doesn't allow colons in class names

[init-dcat-ap-de]

I'm trying to use mermaid for creating an class diagram in a semantic web context. There, colons are needed for prefixes:

    class dcat:Dataset {
        <<mandatory>>
    }

_Also an issue for @persidskiy , see https://github.com/mermaid-js/mermaid/issues/1266#issuecomment-643793801_

@init-dcat-ap-de and @persidskiy, Did you find any workaround for this ?

Unfortunately yes: Switching to PlantUML.

I will focus on this issue and see if I can make it work
