How to exclude an enumeration value in an XML file using XSD?

Question

Is it possible to specify a tag value or the attribute should not be like some_value ?

I have a strange requirement when xsd does not know what values ​​are sent to it. The value of this particular tag can be a string with any value except one value (say data_migration).

The sender must be acknowledged with an error if this particular value is sent.

Can this restriction be specified?
