Class diagrams with links export to syntactically incorrect SVG files

[wouterbeek]

When a class diagram contains at least one link, the generated SVG contains a syntax error:

XML Parsing Error: prefix not bound to a namespace
Location: FILE
Line Number ROW, Column COLUMN:

Steps to reproduce the behavior:

1. Store any class diagram with at least one link in a file example.mmd (e.g., the example from the Mermaid website, see below).
2. Run mmdc -i example.mmd -o example.svg
3. Open the SVG image in a program that can display SVGs (e.g., Firefox); observe the syntax error.

classDiagram
  class Shape
  link Shape "http://www.github.com" "This is a tooltip for a link"

Expected behavior

SVGs generated with mmdc without errors/warnings to be syntactically valid.

@wouterbeek : mermaid-cli is only a thin layer over mermaid library. I suggest to report your issue here https://github.com/mermaid-js/mermaid/issues

@MindaugasLaganeckas Thanks, I've adding it over at mermaid-js/mermaid#1592.

This was the first diagram that I created :-P
