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