Bug description:  DOM->schemaValidate causes an access violation

Description:
------------
When an unescaped & is encounted in an XML document, PHP causes an access
violation in IIS when DOM schemaValidate or DOM schemaValidateSource is
called.
I have PHP running as an ISAPI module using the php5isapi.dll

Reproduce code:
---------------
<?php
$sXML = '<?xml version="1.0" encoding="ISO-8859-5"?>
<root type="input" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="input.xsd">
<username>Jona&</username>
</root>';

$sSchema = '<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:simpleType name="string">
	<xs:restriction base="xs:string">
		<xs:minLength value="1" />
	</xs:restriction>
</xs:simpleType>

<xs:element name="root">
	<xs:complexType>			
		<xs:choice>
			<xs:element name="username" type="string" />
			<xs:element name="password" type="string" />
		</xs:choice>
		<xs:attribute name="type" type="xs:string" use="required"
fixed="input"
/>
	</xs:complexType>
</xs:element>
</xs:schema>';

$obj_DOM = new DOMDocument("1.0", "ISO-8859-5");
$obj_DOM->loadXML(trim($sXML) );

$obj_DOM->schemaValidateSource($sSchema);
?>

Expected result:
----------------
Warning thrown along the lines of "Invalid XML document" or schemaValidate
returns false.

Actual result:
--------------
PHP has encountered an Access Violation at 01B1E093
Warning: DOMDocument::loadXML() [function.DOMDocument-loadXML]:
xmlParseEntityRef: no name in Entity, line: 3 in
D:\www\php5api\webroot\xml_schema_test.php on line 27
