| Check that a document with type "text/x-pseudo-xml" is not parsed as XML. | |
| Do XML documents fetched using XMLHttpRequest have script run? Have XML Stylesheet PIs loaded? | |
| Do responseXML and responseText return null or raise exceptions when not ready? | |
| Does .abort() send readyState to 0 and leave the event listeners? | |
| Do headers with U+000A, U+000D, U+0020, U+003A characters cause it to be dropped? |
