title: Editing content of custom tags in VisualEditor (MediaWiki)?
body: <p>is it possible to make custom MediaWiki tags (as described <a href="https://www.mediawiki.org/wiki/Manual:Tag_extensions" rel="nofollow">here</a>) edit-able in VisualEditor?</p>
  
  <p>When it is (which I guess) - are there <em>any</em> resources on this topic? I know there is no real documentation for VisualEditor, but I guess a lot of people had to do this, so maybe someone wrote down what he did? </p>
  
  <p>I guess I have to extend the VisualEditor Data Model and add translations between it and HTML for what my specific tags do, but I can't real find where/how to do so.</p>
