Markdown segmentation

@Dima Thanks. I just tried this for a markdown file. The rule I want to add is to create a split after an aside (tip, warning, note) using the vuepress format. That will then mean that if I change my asides later, at least only the string for the aside is changed - not the content:

     <!-- Split after :::warning or tip or note or info or caution -->
      <rule break="yes">
          <beforebreak>:::\s*?(warning|info|tip|caution|note)</beforebreak>
          <afterbreak>.*?</afterbreak>
      </rule>

My question though, is how do I apply this to the existing markdown set without modifying the existing default rules? All the segmentation rule examples assume you provide a whole rule file, but I’d prefer just “append” this rule because there might be others that I am missing (lots of unintended consequences).

If not, then I need to know the default rules so I can include the whole file - do you know what they are?
