Make it work with XHTML5 documents (content type application/xhtml+xml and no DOCTYPE)

[mildred]

When a page is loaded as XHTML, script execution is a little different. The most obvious is that document.write is not available, but there are a few catches here and there that makes Aloha not perform as well as if the document was served with text/html content type.

• XHTML5 documents don't have a doctype declaration, because there is no HTML5 DTD. Consequently, non-XML entities (such as  ) are not available. These should not be used (  should be replaced with  )
• innerHTML will throw an error when given non valid XML string. This means that opened tags should be closed when they have attributes. $("<div>") will not throw an error but $('<div class="test">') will throw an error and should be replaced by $('<div class="test"></div>')
• the same for tags that auto-close. For instance <input ...> should be replaced by <input .../>.

To which AE version are you refering to?

The dev branch mostly. The fix are quite simple there, see my repository.

I however experience some issues on the hollowing-mad as well (commit branch7db577f16b5477ca4dc5b4dfb3813e1bcdc010f2). I haven't looked up further into this issue, but the symptom is that whenever I try to apply some formatting to selected text it doesn't work (although there is some change, mostly to the cursor).
