RFE: Integrate Critic Markup into AsciiDoc

Hey there!

I've come across CriticMarkup and I think something /like/ CriticMarkup would
be a useful addition to AsciiDoc:

    "CriticMarkup was designed to make plain text copyediting markup easy to
    write and easy to read."

ATM AsciiDoc supports comments, but none of the other elements regularly used
in copyediting text. This is where CriticMarkup comes in by adding these
elements:

* Addition {++ ++}
* Deletion {-- --}
* Substitution {~~ ~> ~~}
* Comment {>> <<}
* Highlight {== ==}{>> <<}

Something like this would certainly make copyediting of documentation we
(sys4) work on easier. ATM we use comments in merge request, but they are not
part of the document and its history.

Opinions?

P.S.
Yes, this should probably go to a list that discusses AsciiDoc as a standard
and not the asciidoctor tool.

That I've tried in the past (as technical prototype) as critics markup is not available:

1. Marking block manually as added/removed using roles

   ++++
   <style>
   .removed{background-color: #fdb8c0}
   .added{background-color: #acf2bd}
   </style>
   ++++
   
   Hello [.added]##to the ##world! This [.removed]##an##[.added]##a## test!
   

   Produces:
2. Post-processing HTML output of a new version and an old version using HTML-diffing (for example NPM package htmldiff-js). This leads to very similar results, but will highlight all changes in the HTML. A very minimal live prototype is here: https://asciidoc-editor.ahus1.de; once you edit a file, you can toggle the preview to show you a HTML-diff

We use the same approach here (defining roles). But I second Patrick's request!
