The related field of an object must not use the value of '0' as this is the wildcard value.
The instance identifier of the source field of an object must not use the value of '0' as this is the wildcard value.

<mal:service xsi:type="com:ExtendedServiceType" name="Event" number="1"
comment="An event is a specific object representing 'something that happens in the system at a given point in time'. The event service provides a generic mechanism for the distribution of events.
An event is a special type of COM object and is identified by the normal object fields (domain, object type, and object instance identifier). 
It may also contain:
<ul>
 <li>a link to a source object (that caused the event to be generated)</li>
 <li>a link to a service specific related object</li>
 <li>a body that is specific to the event type and whose data structure is defined by the service that declares the event.</li>
</ul>
The event service only defines a single operation that supports the publishing of events and subscription of events generated by other components.
Events are published with a MAL update type of DELETION. Events are something that happens at a given point in time, therefore they in themselves have no lifetime, they are created and deleted at the time instant in time. For efficiency purposes only the deletion update is used.">

comment="The MAL::EntityKey.firstSubKey shall contain the event object number as a base 10 string. For example, for an object number of '14' the key value would be '14' with no padding.
The MAL::EntityKey.secondSubKey shall contain the area, service, and version ObjectType fields as a MAL::Long populated as (in hex) 0xAAAASSSSVVXXXXXX where AAAA is the area (16 bits), SSSS is the service (16 bits), VV is the version (8 bits), and XXXXXX is unused and set to zero (24 bits). For example, for an area of '1', and a service of '2', and a version of '3' the field would contain (in hex) 0x0001000203000000.
The MAL::EntityKey.thirdSubKey shall contain the event object instance identifier.
The MAL::EntityKey.fourthSubKey shall contain the area, service, version and number fields of the event source ObjectType using same methodology as given for the second sub key but replacing the XXXXXX part with the number field.
The related and source links of the event shall populate the ObjectDetails part of the publish/notify message.
The body of the event shall populate the final part of the publish/notify message.
The timestamp of the Event shall be taken from the publish message.
An event in one domain may be generated by something in another domain therefore the domain of the event shall not be required to be the same domain as the source of the event.">

<mal:service xsi:type="com:ExtendedServiceType" name="Archive" number="2"
comment="The Archive service provides a basic interface to a standard archiving function. It follows the basic CRUD principles and allows simple querying of the archive. It provides operations to add new objects to an archive, delete objects from an archive, update existing objects in an archive, and also query the content of the archive.
The query operation provides a basic querying ability, allowing a consumer to filter on fields from the object headers (such as domain etc) and also filter on the body of the object if it uses the MAL data type specification.
The query operation is extensible but the extensions would be outside this standard.
Finally, a consumer of the archive can monitor it for changes by subscribing for archive events from the event service. Any change to the archive is published using the event service if it is supported by an implementation.">

The OperationActivity object shall use the transaction identifier of the MAL operation for its object instance identifier.

All Activity events for the interaction shall link to the OperationActivity object using their source link where the object instance identifier to use is the MAL interaction transaction identifier.
If a relay node is unable to relay the operation then that relay shall fail the MAL interaction that the consumer initiated as well as generate the correct activity event.
The executionStage field of the Execution event structure shall hold the current execution stage of the activity.
For SUBMIT, INVOKE, and PROGRESS interactions the ACKNOWLEDGE stage shall have an execution stage value of '1'.
For REQUEST interactions the RESPONSE stage shall have an execution stage value of '1'.
For PROGRESS interactions the execution stage value for the PROGRESS updates shall start at '2' and increate for each update sent.
