[bpel4people] NEW ISSUE: Title: addAttachment API call is missing the content type param

["Mark Ford" <mark.ford@activevos.com>]

TARGET: HT API

DESCRIPTION: The element defined for the addAttachment operation does not
have a means for indicating the content type. 

PROPOSAL: Add the attachment type to the element. This involves a change to
ws-humantask-api-wsdl.xsd.

Current definition:

  <xsd:element name="addAttachment">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="identifier" type="xsd:anyURI" />
        <xsd:element name="name" type="xsd:string" />
        <xsd:element name="accessType" type="xsd:string" />
        <xsd:element name="attachment" type="xsd:anyType" />
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>

Proposed definition:

  <xsd:element name="addAttachment">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="identifier" type="xsd:anyURI" />
        <xsd:element name="name" type="xsd:string" />
        <xsd:element name="accessType" type="xsd:string" />
        <xsd:element name="contentType" type="xsd:string" />
        <xsd:element name="attachment" type="xsd:anyType" />
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
