Type of expectedMediaType element ??

Is the type of expectedMediaType element a string or list of string?

According to prose  [1], "The type of the expectedMediaType element
information item is xs:string. The value of the expectedMediaType element is
similar to the value allowed for the 'Accept' header defined by HTTP 1.1
specification, Section 14.1 [IETF RFC 2616]."

According to schema [2], "
   <xs:element name="expectedMediaType" >
    <xs:simpleType>
     <xs:list itemType="tns:expectedMediaTypeItem" /> .."
