Hello,

The following error is reported in Oxygen XML but the parser does successfully validate my XML document against the given XSD:  "Description: TargetNamespace.2: Expecting no namespace, but the schema document has a target namespace of 'http://schemas/jupiter'."

Otherwise it appears to work. If I change noNamespaceSchemaLocation to schemaLocation the error changes to "There is no schema or DTD associated with the document" and the validation stops working. It appears that not using a namespace is not an option because the type used to validate the currency-short-name must be qualified with a namespace.

I would like this error to go away and ultimately have this properly defined.

Thank you,
Peter

Sample.xml
 
<?xml version="1.0" encoding="ISO-8859-1"?>
<jupiter:estimate name="XXX" description="X" rev-number="X"
    notice-to-proceed="2009-09-30" status="In Process" base-currency="EUR"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:jupiter="http://schemas/jupiter" xsi:noNamespaceSchemaLocation="Jupiter.xsd"
    >
    <estimate-currency name="US Dollar" short-name="USD" exchange-rate="0.800000"/>
    <estimate-currency name="Euro" short-name="EURx" exchange-rate="1.000000"/>
 
Note: The above line correctly fails validation because EURx is not a valid currency-short-name-type

xsi:noNamespaceSchemaLocation="Jupiter.xsd"

needs to become

xsi:schemaLocation="http://schemas/jupiter Jupiter.xsd"

if there is a targetNamespace, you need to point to it
before the space is the namespace, after the space is the location of the schema

Thank you, that worked! Does anything appear embarrassingly out of kilter that I should look at?

Welcome
Nothing embarrassing in this, it is a bit tricky anyway
It is the schema that decides whether you have a namespace or not in your XML
so if there is no targetnamespace in the schema use the reference as you did
if there is a target namespace, you need to reference that as well,
a bit perculiar, don't worry, now you know
