RecordType (1 byte): This octet MUST be set to 0x08 to indicate that this is a Fault record.
FaultSize (variable): The value MUST be set to the size, in octets, of the fault, and encoded based on the scheme that is described in section 2.2.2. The size MUST NOT be set to 0.
Fault (variable): A URI (as defined by [RFC2396] except that the "escaped" construct is never used). The URI is encoded by using UTF-8. The following table defines a collection of faults. An implementation MAY support these fault values and MAY also define new ones.<7>
-
For convenience, in this description the URI is broken into a namespace and fault name. The namespace for faults in the following table is http://schemas.microsoft.com/ws/2006/05/framing/faults/. Any additional faults that are defined MUST NOT use this namespace.
-
An example of a fault, as returned in a Fault Record, is the following: http://schemas.microsoft.com/ws/2006/05/framing/faults/UnsupportedMode
