Remarks

To get XmlSchemaCollection object properties, users can be a member of the public fixed server role.

To set XmlSchemaCollection object properties, users must have ALTER permission on the XML schema collection.

To create an XML schema collection, users must have CREATE XML SCHEMA COLLECTION permission on the database or be a member of the db_owner fixed database role.

To drop an XML schema collection, users must have DELETE permission on the XML schema collection.

To grant, deny, or revoke permissions on the XML schema collection to other users, users must have CONTROL permission on the XML schema collection.
