Structured document conformance

[AlexLloyd0]

I have a library which uses the HTML-ARIA document conformance data from https://www.w3.org/TR/html-aria/#docconformance.

I parsed the table into a protocol buffer text representation (sample below). A few thoughts:

1. Something like this would be useful to other projects building accessibility tools. Should some machine-readable format be included in this repo?
2. Defining the document conformance rules in a structured format could prevent human-error and ensure implicit aria semantics are well-defined. The table in the spec could even be generated from this definition.

Looking for input from the repo owners whether you'd be interested in 1. or 2.

    condition {
      attribute_takes_value {
        attribute: "role"
        value: "textbox"
      }
    }
  }
  equivalent {
    condition {
      tag_name: "textarea"
    }
  }
  equivalent {
    condition {
      tag_name: "input"
    }
    condition {
      attribute_takes_value {
        attribute: "type"
        value: "text"
      }
    }
    condition {
      absent_attribute: "list"
    }
  }
