Hi Eran,

My reply inline.

All Gurus, please see my related question too inline.

SOAP 1.2 states that all application defined elements that give more detail
on the error shd go  as "Detail Entries" into the "Detail" element
information item within the Fault element info item. The specification also
clearly says - "When generating a fault, SOAP senders MUST NOT include
additional element information items in the SOAP Body . A message whose Body
contains a Fault plus additional element information items has no
SOAP-defined semantics."

Gurus, two questions here.
1) [Section 5.4.5 of SOAP 1.2 Part 1] SOAP 1.2 states the following - "All
child *element information items* of the Detail *element information
item*are called detail entries ".
This means that the "Detail" element information item  can have multiple
detail entries. Does that mean that the user shd be able to define multiple
element info items while describing a Fault in a WSDL Document, or cd the
child elements of a fault element in the WSDL be directly copied under
the <Detail> element in a SOAP Fault EII ?

2)  [Section of SOAP 1.2 Part 1] states that "Each detail entry MAY
have a [namespace name] property which has a value, that is the name of the
element MAY be namespace qualified." This means that the detail entries may
alternatively come from "null/No Namespace". How wd a user be able to model
this in a WSDL description ?

Usage of WSDL 2.0 or 1.1 should not affect the place where application
defined elements should go into a SOAP Fault Message, since this is governed
by SOAP 1.2 specification.
