ids:Message
Core ids:Message class with it's properties, which are equal for all messages. For communication in the IDS, use the specific message types.
Properties of ids:Message
Table of Message Properties
ids:correlationMessage
Correlated message. Usually needed, if a messages responds to a previous
TODO: MessageProcessedNotification >>> MessageProcessedNotification? message. A Connector may, e.g., send a MessageProcessedNotification` as a response to an incoming message and therefore needs this property to refer to the incoming message.
ids:securityToken
The mandantory property ìds: securityToken contains (value) a token, representing a claim, that the sender supports a certain security profile. This token is called Dynamic Attribute Token (DAT), (see further explanations there), so it is an instance of ids:DynamicAttributeToken and will be provided by Dynamic Attribute Provisioning Service (DAPS).
Message Types
The table contans descriptions for each message, information about the payload as well as changes in the properties, i.e., new properties and additional mandatory properties. "Message Class" and "Message Subclass" are just for structural / hierarchical descriptions. The "Message Name" contains the actual Message which is used.
New properties, which are mandatory are marked with an (*). Existing properties, which are mandatory for a specific messages are listed in the corresponding column.
All mandatory property declarations of the core ids:Message above still hold. Optional properties are supported but not required.

Request Messages
ids:RequestMessage
ids:DescriptionRequestMessage
Message requesting metadata.
