Not all of the types mentioned in the note are represented by the subfeatures. The PR title had me anticipating keys like this:

  • html.elements.datalist
  • html.elements.datalist.input_type_color
  • html.elements.datalist.input_type_date
  • html.elements.datalist.input_type_email
  • html.elements.datalist.input_type_number
  • html.elements.datalist.input_type_range
  • html.elements.datalist.input_type_search
  • html.elements.datalist.input_type_tel
  • html.elements.datalist.input_type_text
  • html.elements.datalist.input_type_time
  • html.elements.datalist.input_type_url

This PR only extracts these four from existing data:

  • html.elements.datalist.input_type_color
  • html.elements.datalist.input_type_date
  • html.elements.datalist.input_type_range
  • html.elements.datalist.input_type_time

The current data suggests to me the following textual types were always supported:

  • html.elements.datalist.input_type_email
  • html.elements.datalist.input_type_number
  • html.elements.datalist.input_type_search
  • html.elements.datalist.input_type_tel
  • html.elements.datalist.input_type_text
  • html.elements.datalist.input_type_url
