Bug description:SimpleXMLIterator supports ArrayAccess without implementing Interface

Description:
------------
This is more of a consistency issue, but I'm submitting it as a bug since
it prevents certain type checks in PHP code.

SimpleXMLIterator does not implement the ArrayAccess interface (and neither
does its parent SimpleXML).  And the documentation says nothing about
access via array syntax.  However the class itself does support that method
of access.  

To resolve the issue, two things can be done. 

First, documentation should be updated to reflect that method of access.

Second, SimpleXMLIterator should implement the ArrayAccess interface for
consistency...



Test script:
---------------
$xml = '<items><item>foo</item></items>';
$simple = simplexml_load_string($xml);
var_dump($simple->item instanceof ArrayAccess);
print (string) $simple->item[0];

Expected result:
----------------
bool(true)
foo

Actual result:
--------------
bool(false)
foo
