Jira issue originally created by user andrew.mcconnell:
The metadata XSD at http://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd defines the element on line 66 as . This allows for no more than one element though the documentation at http://www.doctrine-project.org/docs/orm/2.1/en/reference/xml-mapping.html#defining-identity-and-generator-strategies states that more than one element is allowed.
