| 28 // A document's "DOM tree accessors" include: |
| 29 // (document.)head, title, body, images, embeds, plugins, links, forms, |
| 30 // scripts, getElementsByName(), cssElementMap, and currentScript |
| 31 // |
| 32 // Of these, it is unclear how document.cssElementMap can be tested. |
| 33 // Except for it, there is a test corresponding to each accessor. |
| 34 // |
| 35 // Additionally, there are obsolete accessors |
| 36 // <http://www.whatwg.org/specs/web-apps/current-work/multipage/obsolete.html#ot
her-elements,-attributes-and-apis>: |
| 37 // (document.)anchors, applets, and all. |
| 38 // |
| 39 // and some accessors defined in the DOM specification (formerly known as |
| 40 // "DOM Core") <http://dom.spec.whatwg.org/#interface-document>: |
| 41 // (document.)documentElement, getElementsByTagName(), |
| 42 // getElementsByTagNameNS(), getElementsByClassName(), and getElementById(). |
| 43 // |
| 44 // As it seems reasonable to have tests for these accessors, this file also |
| 45 // includes tests for them, except for document.documentElement which is |
| 46 // unclear whether we can test; the distribution process of Shadow DOM does not |
| 47 // alter the host element, so the document element (e.g. <html>) cannot be |
| 48 // replaced with an element in a shadow tree. |
