Additional context

I use this diagram type to make models of RDF graphs. It would be great if I can use the namespace prefixes with the appropriate syntax inside the labels to support reuse of these diagrams into making actual RDF

Closing this as this is a MermaidJs bug, and not Mermaid Chart. See this issue: mermaid-js/mermaid#4488
