How to support HTML Comments?

[cjenkscybercom]

Trying to extend this library so that it has feature parity with a Java client that allows (but doesn't render) HTML comments. Haven't found any existing plugins that do this, and the html: true option does support this but it also supports <script> tags so that's a no-go. Also, typical workarounds like empty links don't work.

Use case for comments is a templating scenario, like how GitHub supports issue templates; inside the markup, you have comments explaining what each of the sections are for.

It seems like what I need to do is write a block and inline rule (since comments can be inline or across many lines) that generate maybe COMMENT_START and COMMENT_END tokens, and then a renderer that consumes those tokens?

Any suggestions welcome!
