GEIA-STD-0007

Can anyone help me with obtaining the schema for GEIA-STD-0007? This is a Logistics product data vocabulary. I have the handbook for the standard which describes, in great detail, all of the elements. But there is actually copy of the .xsd. The namespace in some sample XML instances I have is 'xmlns:geia="http://www.geia_STD_0007.com/2006/schema"' but the URL does not exist.

I am writing a transform from a MIL-STD TM vocabulary to the GEIA-STD-0007 and would like to be able to validate the output.
