SimpleXML is an extension, but it only works with PHP 5 because it
relies upon many low-level features that are only available in Zend
Engine 2, such as property and method overloading and
iterators.

(There are additional reasons, such as SimpleXML expecting to work in
conjunction with PHP 5's base libxml2 extension, but the ones listed
first are the most fundamental.)
