Below is the post that I made last week to the W3C Schema mail list 
... I still have not seen any response to the post, so I still do not 
know the answer to the question.

The UBL TC is meeting face-to-face this week so we need help as soon 
as possible ... I hoping that someone on the UBL-Dev or XML-Dev list 
might offer comments on the situation described below.

Thanks again for bringing this up!

Subject: Question of reports of non-determinism

Hello all,

Below is transcript of an extended example from our work in UBL:

   http://www.oasis-open.org/archives/ubl/200604/msg00013.html

I've been using xjparse invoking Xerces in order to test examples and 
experiments for the TC.

In the example below, I have modeled an extension point named 
LineItemExtension into which I wish to allow child elements from any 
other namespace and from no namespace.

I am informed that some tools (not Xerces below) report that ##other 
conflicts with ##local in that it is non-deterministic.  Yet if I 
take out ##local the example below fails in Xerces because I've 
included an element in no namespace, so Xerces is implementing "other 
namespace" as "other non-null namespace", while the other tools are 
implementing "other namespace" as "other namespace including no namespace".

Does ##other imply ##local or does ##other require there be a target 
namespace that is different in the particle?  If ##other implies 
##local then Xerces is wrong ... otherwise these other tools are wrong.

I'm looking to advise the TC correctly in this matter, so any help 
would be greatly appreciated.

Thanks!
