Response to invalid XML?

"Section 2.4 XML Decoding says in part:

• • • • • 
          However an OBIX parser MUST never accept an XML document which isn't well formed (such as mismatched tags).

But the SOAP binding document says:

2.2 Error Handling: ""The OBIX specification defines no SOAP faults. If a request is processed by an OBIX server, then a valid OBIX document SHOULD be returned with a failure indicated via the err object.""

I may have over looked it but what response, if any, does a server return for non-well-formed XML? Reasoning that a client could simply keep resending without any response or ability to signal non-receipt of the XML based message.

In reading 10.2 of OBIX 1.1, the server ""successfully receives a request"" which I assume means the message has not been rejected due to malformed XML. Yes?
