context structure and mustUnderstand/mustPropagate

["Mark Little" <mark.little@arjuna.com>]

If we look at the current context:

 

<xs:complexType name="ContextType">
 <xs:sequence>
  <xs:element name="context-identifier" type="xs:anyURI"/>
  <xs:element name="activity-service" type="xs:anyURI" minOccurs="0"/>
  <xs:element name="type" type="xs:anyURI" minOccurs="0"/>
  <xs:element name="activity-list" minOccurs="0">
   <xs:complexType>
    <xs:sequence>
     <xs:element name="service" type="xs:anyURI" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
    <xs:attribute name="mustUnderstand" type="xs:boolean" use="optional" default="false"/>
    <xs:attribute name="mustPropagate" type="xs:boolean" use="optional" default="false"/>
   </xs:complexType>
  </xs:element>
  <xs:element name="child-contexts" minOccurs="0">
  <xs:complexType>
   <xs:sequence>
    <xs:element name="child-context" type="tns:ContextType" maxOccurs="unbounded"/>
   </xs:sequence>
   </xs:complexType>
  </xs:element>
  <xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
 </xs:sequence>
 <xs:attribute name="timeout" type="xs:int" use="optional"/>
</xs:complexType>

 

the   idea  was  that   the  ##other   would  be  the  ALSs  extension
element.   However, this and other   things  about the current context
structure   are    broken (possibly   cut-and-paste  errors  in   some
cases). For example, the mustUnderstand attribute is meant to apply to
a specific ALSs data, and not to the activity-list.

 

With that in mind, the context should probably look like:

 

<xs:complexType name="ContextType">
 <xs:sequence>
  <xs:element name="context-identifier" type="xs:anyURI"/>
  <xs:element name="activity-service" type="xs:anyURI" minOccurs="0"/>
  <xs:element name="type" type="xs:anyURI" minOccurs="0"/>
  <xs:attribute name="timeout" type="xs:int" use="optional"/>
  <xs:element name="activity-list" minOccurs="0">
   <xs:complexType>
    <xs:sequence>
     <xs:element name="service" type="xs:anyURI" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
   </xs:complexType>
  </xs:element>
  <xs:element name="als-data" minOccurs="0">
   <xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
   <xs:attribute name="mustUnderstand" type="xs:boolean" use="optional" default="false"/>
   <xs:attribute name="mustPropagate" type="xs:boolean" use="optional" default="false"/>
  </xs:element>
  <xs:element name="child-contexts" minOccurs="0">
   <xs:complexType>
    <xs:sequence>
     <xs:element name="child-context" type="tns:ContextType" maxOccurs="unbounded"/>
    </xs:sequence>
   </xs:complexType>
  </xs:element>
 </xs:sequence>
</xs:complexType>
