Question

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

I have a strange requirement, where the xsd isn’t aware of the values being sent to it. The value of that particular tag can be a string with any value except one value ( say data_migration).

The sender should be acknowledged with the error, if that particular value is sent.

Is it possible to specify this restriction?

I’m no regex expert, but this simpleType makes everything starting with data_migration invalid.

<xs:simpleType name="notDataMigration">
  <xs:restriction base="xs:string">
    <xs:pattern value="^(?!data_migration).*" />
  </xs:restriction>
</xs:simpleType>
