  22 //   number of nodes represented by the collection. If there are no such elements, then there are no
  23 //   supported property indices.
  24 // - The supported property names are the values from the list returned by these steps:
  25 //   1. Let result be an empty list.
  26 //   2. For each element represented by the collection, in tree order, run these substeps:
  27 //       1. If element has an ID which is neither the empty string nor is in result, append element's ID to result.
  28 //       2. If element is in the HTML namespace and has a name attribute whose value is neither the empty string
  29 //          nor is in result, append element's name attribute value to result.
  30 //   3. Return result.
