Protected elements are being outputted without closing tags.

[Martin Kou]

Run the following code in Firebug, with replacebyclass.html sample opened:

var editor = CKEDITOR.instances.editor1;
var o = new CKEDITOR.dom.element('object', editor.document);
o.append(new CKEDITOR.dom.element('embed', editor.document));
var i = editor.fakeobjects.protectElement(o);
editor.document.getBody().append(i);

An object with an embed tag inside is inserted to the document. Now switch to Source mode. The HTML output reads like this:

<p>
	This is some <strong>sample text</strong>. You are using <a href="http://www.fckeditor.net/">FCKeditor</a>.</p>
<object><embed></object>

Note the <embed> tag doesn't have a closing tag, and it's not self closing.

Not sure if it's ok to modify the dtd.js for this purpose.

After some discussion with Fred, it shouldn't be required to add embed to dtd.js for it to appear - that's a bug in the htmldataprocessor plugin. So instead of hacking dtd.js, a fix for htmldataprocessor is required.

Ok, so how to protect EMBED element?

This code:

var a= editor.document.createElement( 'embed' );
editor.fakeobjects.protectElement( a );

doesn't work.

This is a dup of #2860, which is already fixed.
