For the Doc/Lit format, an array parameter is represented as a sequence of its data type in an XML Schema type definition:

Array parameter definition for Doc/Lit WSDL

<complexType
  <sequence>
    <element name="paramName" type="XMLType"
             minOccurs="zero_or_extentval"
             maxOccurs="extentval_or_unbounded"/>
  </sequence>
</complexType>

The bolded elements refer to:

  • paramName — The name of the parameter
  • XMLType — The XML Schema type of the parameter
  • zero_or_extentval — 0 or an integer for the minimum array size
  • extentval_or_unbounded — An integer for the maximum array size or unbounded

The Doc/Lit WSDL for arraySample has the following types and message sections:

<wsdl:types>
  <schema targetNamespace="urn:tempuri-org:CustomerAO"
          xmlns="http://www.w3.org/2001/XMLSchema"
          elementFormDefault="qualified">
    <element name="arraySample">
      <complexType>
        <sequence>
          <element name="names" type="xsd:string" minOccurs="0"
                   maxOccurs="unbounded" nillable="true">
          <element name="hireDates" type="xsd:dateTime" minOccurs="0"
                   maxOccurs="unbounded" nillable="true">
        </sequence>
      </complexType>
    </element>
    <element name="arraySampleResponse">
