I had setup several SP 2016 server in my environment. Recenlty I am getting failed message while running SharePoint Configuration wizard with the below error.
Feature definition with Id ca7bd552-10b1-4563-85b9-5ed1d39c962a failed validation, file 'fieldswss4.xml', line 68, character 9: The 'ListInternal' attribute is not allowed. ---> System.Xml.Schema.XmlSchemaValidationException: The 'ListInternal' attribute is not allowed.
To resolve this we have to add a line in wss.xsd file in Hive\template\XML.
Below Line needs to be added at 578 in XML file next to List attribute.
Search the following bold content in XML file name="List" type="xs:string"
And then include the below line next to the List Attribute
<xs:attribute name="ListInternal" type="xs:string" />
Save the file and re-run the config wizard that's it. Cool.
