Description:
------------
The value parameter must be escaped - putting ampersands in the string will cause an exception. See http://bugs.php.net/bug.php?id=31191

Reproduce code:
---------------
---
From manual page: domdocument.createelement#Parameters
---

"The value of the element. By default, an empty element will be created. You can also set the value later with DOMElement->nodeValue."

Expected result:
----------------
There should be a comment about how the $value parameter must be escaped and that the developer probably should use $document->createTextElement() instead. Perhaps something like this:

"The ampersand-escaped value of the element. By default, an empty element will be created. You can also set the value later with DOMElement->nodeValue. To create a text node with escaping support, leave out this parameter, use DOMDocument->createTextElement() and append the text node to your DOMElement."

Actual result:
--------------
"The value of the element. By default, an empty element will be created. You can also set the value later with DOMElement->nodeValue."
