Contact Information in Metadata
Each <md:EntityDescriptor>
element SHOULD contain an <md:ContactPerson>
element with contactType="support"
as well as an <md:ContactPerson>
element with contactType="technical"
. Each <md:ContactPerson>
element SHOULD contain at least one <md:EmailAddress>
element. If a contact (either support or technical) is a real person, the <md:givenName>
and <md:surName>
elements SHOULD reflect the person's real name. If a contact is a non-person (such as a mailing list), the <md:givenName>
and <md:surName>
elements SHOULD be omitted.
