Would it not be possible to "nest"
the Fault Messages using the wsbf:BaseFault element information item?
(I know this doesn't use the preferred
approach of declaring a new extension with base="BaseFaultType",
but I wanted to keep the example simple)
<BaseFault>
<Timestamp>...</Timestamp>
<ErrorCode dialect="ZOSError">abend1234</ErrorCode>
<Description
xml:lang="geek">something really technical </Description>
<FaultCause>
<BaseFault>
<Timestamp>...</Timestamp>
<ErrorCode dialect="JavaExceptionClass">com.ibm.zos.errors.Exception</ErrorCode>
?
<Description>INSERT exception trace HERE</Description>
*
</BaseFault>
</FaultCause>
</BaseFault>
You are correct that none of the element
information items in BaseFault support open attribute or open element extensibility.
We considered that the nesting approach would address the approach
you suggested.

[wsrf] WS-BaseFault & Java |
We've been struggling a little with how to present
a Java exception
stack trace to clients:
* The ErrorCode field seems very much geared towards
presenting
legacy error codes and has a maxOccurs of 1
so we would not be
able to communicate the stack trace and the
error code if the
stack trace were caused by a error in a legacy
call
* The Description field should contain a plain language
description of the fault. Again, not exactly
a perfect fit.
The solution we see is to either rename ErrorCode to something more
generic, say ErrorDetails, and change maxOccurs to unbounded or to allow
the annotation of the Description field with something indicating it's
content (we may only want to present certain type of content to the user
at the default setting).
In general I feel that both the ErrorCode and Description elements
should have been declared allowing for attribute extensibility as you
can't (afaik, please correct me if I am wrong, I'm not a schema expert)
add attributes to these elements via schema extension.
