SBVR14 — Error message from XML Schema validator when trying a SVBR XSD

We're currently building a Corporate Vocabulary and our idea is to use the SVBR provided XML Schema for all source documents.

However, when trying the XSD-file available at the SVBR specification page in an XML Schema validator a got the error message:

Src-import.3.1: The Namespace Attribute, 'http://schema.omg.org/spec/XMI/2.1', Of An <import> Element Information Item Must Be Identical To The TargetNamespace Attribute, 'http://www.omg.org/spec/XMI/20071213', Of The Imported Document.

The XML Schema validator is available at the URL:
http://www.freeformatter.com/xml-validator-xsd.html

I have a sceen dump as well that I can send via email.

I downloaded the XSD-file and changed the namespace to match the namespace in the import element.
But it only resultet in a new fault.

Any ideas?

Deferred to SBVR v1.5 Revision Task Force because the SBVR v1.4 RTF was requested to close before it was finished so the SBVR RTF could be convert to JIRA.
