Hi,



I have a question regarding the CAP specification for my clarification.



A new CAP message is identified by the "identifier" element. The
identifier is unique for the message. I assume that when the message is
updated (as specified by the "msgType" element), the identifier will
have another value.



Is this assumption correct?



When the original message needs an update or a cancellation, the
"msgType" element is used to indicate that the new message is in effect
an update or a cancellation of an earlier message. To determine which
message needs updating, the original message is referred to in the
"references" element. This element contains the "identifier" of the
original message.



Is the original message referred to or merely the most recent update?



Example:

Let's assume that the first message is an "Alert" message, followed by
an "Update", and then finally cancelled by a "Cancel" message. Does the
reference in the "Cancel" message contains the identifier of the
"Update" message, or does it contain the identifier of the original
"Alert" message?



Thanks and kind regards,



Peter Sanders
