Do not use CDATA to concatenate data
The following code block is not correct.
<ResourceContributor> <PartyName> <FullName> <![CDATA[Anne Sofie von Otter [Contralto] & Susan Addison [Trombone] & Barbara Bonney [Soprano] & Hans Peter Blochwitz [Tenor] & Sir Willard White [Bass] & English Baroque Soloists [Orchestra] & John Eliot Gardiner [Conductor] & Mozart, Wolfgang Amadeus [Composer]]]> </FullName> </PartyName> </ResourceContributor>
Instead please separate the contributors out as follows (note that this also separates out the composer as an indirect contributor). The following code uses ERN-3 syntax.
<ResourceContributor> <PartyName> <FullName> Anne Sofie von Otter </FullName> </PartyName> <ResourceContributorRole UserDefinedValue="Contralto">Soloist </ResourceContributorRole> </ResourceContributor> <ResourceContributor> <PartyName> <FullName> Susan Addison </FullName> </PartyName> <ResourceContributorRole UserDefinedValue="Trombone">Soloist </ResourceContributorRole> </ResourceContributor> ... <ResourceContributor> <PartyName> <FullName> John Eliot Gardiner </FullName> </PartyName> <ResourceContributorRole>Conductor</ResourceContributorRole> <ResourceContributor> <IndirectResourceContributor> <PartyName> <FullName> Wolfgang Amadeus Mozart </FullName> </PartyName> <IndirectResourceContributorRole>Composer</IndirectResourceContributorRole> </IndirectResourceContributor>
