Bug 484: Fix XmlDocumentUtils.toDocument to handle anyxml

For anyxml data, a ClassCastException occurs at
XmlDocumentUtils.createXmlRootElement(XmlDocumentUtils.java:180) when
blindly casting the schema instance to DataNodeContainer - the actual
instance is an AnyXmlSchemaNode. To prevent this, the code should first
check "schema instanceof DataNodeContainer". 'childSchema' will be null
but that's expected for anyxml as it doesn't have a schema.
