------
A SOAP 1.2 envelope can contain only Header and Body
A SOAP Body element cannot have non Namespace qualified attributes
A SOAP Envelope element cannot have non Namespace qualified attributes
A SOAP Header element cannot have non Namespace qualified attributes
Bad Request

DTD are not supported by SOAP
encodingStyle cannot be specified on the Body
encodingStyle cannot be specified on the Envelope
encodingStyle cannot be specified on the Header
Error cannot find parameter

looks like we got "Body" with several functions call
looks like we got "Body" without function call
looks like we got no XML document
looks like we got XML without "Envelope" element
Missing parameter
mustUnderstand value is not boolean
SoapClient::__doRequest() failed
SoapClient::__doRequest() returned non string value
Unknown Data Encoding Style
Unknown Error
DataEncodingUnknown


MustUnderstand
--------------
Header not understood
