Hide or Show action buttons in xforms-manager depending on the user

When you create a task, you need to send in some task metadata, and according to the Task Manager Service wsdl, we have 4 different actions available by default.

<xsd:element name="claimAction" type="tns:accessControlType" maxOccurs="1" minOccurs="0"/> 
<xsd:element name="revokeAction" type="tns:accessControlType" maxOccurs="1" minOccurs="0"/> 
<xsd:element name="saveAction" type="tns:accessControlType" maxOccurs="1" minOccurs="0"/> 
<xsd:element name="completeAction" type="tns:accessControlType" maxOccurs="1" minOccurs="0"/>

Each of them is of type accessControlType, as defined:

<xsd:complexType name="accessControlType">
 <xsd:sequence>
  <xsd:element name="user" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/>
  <xsd:element name="role" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/>  
  <xsd:element name="authorized" type="xsd:string" minOccurs="0" maxOccurs="1"/>
 </xsd:sequence>
</xsd:complexType>

If nothing is assigned to those accessControlType, the related action will be available, and thus the button displayed by default.
If an assignment is made, then the action will be available only if the user or role matches.

The related action in designer is simply to create an assignment in the data mapper, on the process task initiating the create-complete pattern.
