Unique Validation across Name and Description

Summary:

How can I write a Validation expression which can validate for uniqueness between a Name and a Description US

Content (please ensure you mask any confidential information):

For example,

Name1 <DescriptionBlank>

4121 Name2

Name2 <DescriptionBlank> (This should throw a validation as Name2 is a description of the node 4121)

I want to check Name and Description Uniqueness across the entire Viewpoint.
