Additional string validation formats

There are a couple of additional string validation formats that we’d find really useful on data fields:

  • JSON string
  • Integer wrapped as a string
  • Decimal wrapped as a string

We’re just using the description field or regex patterns at the moment for this, but it would be more readable to have a validation format for those.

Interesting idea. How would you describe them to make them readable but also understandable to different users?
