Description:
------------
Classes inheriting from SimpleXMLElements should be able to have class properties the same way any other class does.
Currently SimpleXML treats operations on class properties as operations on the xml part of the object.
There should be a way to adress both seperately.

Reproduce code:
---------------
      class Foo extends SimpleXMLElement
      {
            public $bar;
      }
      
      $str = "<xml></xml>";
      
      $foo = new Foo($str);
      $foo->bar = array();

Expected result:
----------------
Assigning anything to Foo->bar should not affect the XML part but should be handled as a normal class property.

Actual result:
--------------
SimpleXMLElement tries to interpret the public variable as an XML Element, causing a warning:

Warning: It is not yet possible to assign complex types to properties

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Short answer no.

SimpleXML is designed in a way that properties map to sub elements or attributes depending on the current level. So we cannot have some of those mapping to pure properties. What you want is wrapping SimpleXML instances in your own class (has-a design).
