cannot validate XML against XSD

Question

I keep getting 2 errors trying to process my XML; says it's not a valid OAGIS doc. My XML is simple. The XSD is NotifyCatalog.xsd from OAGIS 9_6_1 When I use xmlvalidation.com it says:

Errors in the XML document: 2: 317 cvc-elt.1: Cannot find the declaration of element 'NotifyCatalog'.

Errors in file xml-schema: 27: 233 TargetNamespace.2: Expecting no namespace, but the schema document has a target namespace of 'http://www.openapplications.org/oagis/9'.

Please help! XML below, XSD is >6000 lines, but I can attach if you like.

Haven't looked at the schema but unless it's a no-namespace schema (unlikely), you should begin your document like this:

<NotifyCatalog xmlns="http://www.openapplications.org/oagis/9"
               versionID="9_4"
               releaseID="9_4"
               systemEnvironmentCode="Production">
...

The xmlns= tells XML the default namespace to assign to elements that don't have a namespace prefix (none of the elements in your document have one, so all will receive the default namespace prefix).

This attribute specification:

targetNamespace:ibts="http://www.openapplications.org/oagis/9"

is bogus (and invalid since targetNamespace isn't a declared namespace prefix); if you wanted to specify ibts as namespace prefix binding, you must use

xmlns:ibts="http://www.openapplications.org/oagis/9"

but as said, you're not using ibts anywhere in the document so you can just remove the assignment.
