Downloading 22-01-03b.zip from:

   http://lists.oasis-open.org/archives/ubl-lcsc/200301/msg00114.html

and my sample instances from:

   http://lists.oasis-open.org/archives/ubl-lcsc/200301/msg00125.html

The schemas as written do not validate the instances:

===8<---
Z:\data\docs\ubl\lcsc\20030122b>msv UBL_Library_0p70_Order.xsd 220order1.xml
start parsing a grammar.
validating 220order1.xml
Error at line:2, column:54 of 
file:///Z:/data/docs/ubl/lcsc/20030122b/220order1.xml
   Probably namespace URI of tag "Order" is wrong (correct one is "")

the document is NOT valid.

When I add the following two attributes to the xsd:schema document element ...

       targetNamespace="urn:oasis:names:tc:ubl:Order:1.0:0.70"
       xmlns="urn:oasis:names:tc:ubl:Order:1.0:0.70"

... the instances validate:

===8<---
Z:\data\docs\ubl\lcsc\20030122b>msv UBL_Library_0p70_Order-mod.xsd 
220order1.xml

No validation errors.

Z:\data\docs\ubl\lcsc\20030122b>msv UBL_Library_0p70_Order-mod.xsd 
220order2.xml

No validation errors.

I am ambivalent about the xmlns:bie="" attribute ... it doesn't affect me, 
it just looks out of place.

Perhaps I've created the instances differently than what members expect ... 
I'm coming in late so I may have incorrect assumptions.  The first lines of 
the 220order1.xml instance are:

===8<---
Z:\data\docs\ubl\lcsc\20030122b>head 220order1.xml
<?xml version="1.0" encoding="UTF-8"?>
<Order xmlns="urn:oasis:names:tc:ubl:Order:1.0:0.70">
   <OrderID>4500004875</OrderID>
   <OrderIssueDate>2001-12-17</OrderIssueDate>
   <OrderTransactionCurrencyCode>USD</OrderTransactionCurrencyCode>
   <OrderGrossWeightMeasure unitCode="kg">50</OrderGrossWeightMeasure>
   <OrderGrossVolumeMeasure unitCode="m3">7</OrderGrossVolumeMeasure>
   <BuyerParty>
     <ID>R300</ID>
     <PartyName>

*I'm* quite confident it is necessary, but I'm concerned that no-one else 
has confirmed or challenged my position.

Any other opinions?  Has anyone else yet created instances against 22-01-03b?
