       altering the message (even if not stored) SHOULD update .meta.lastUpdated. .timestamp
       is used to track the original time of the Bundle, and SHOULD be populated.  

Usage:

* document : the date the document was created. Note: the composition may predate the
       document, or be associated with multiple documents. The date of the composition - the
       authoring time - may be earlier than the document assembly time
* message : the date that the content of the message was assembled. This date is not changed
       by middleware engines unless they add additional data that changes the meaning of the
       time of the message
* history : the date that the history was assembled. This time would be used as the _since
       time to ask for subsequent updates
* searchset : the time that the search set was assembled. Note that different pages MAY
       have different timestamps but need not. Having different timestamps does not imply that
       subsequent pages will represent or include changes made since the initial query
* transaction | transaction-response | batch | batch-response | collection : no particular
       assigned meaning

The timestamp value should be greater than the lastUpdated and other timestamps in the
       resources in the bundle, and it should be equal or earlier than the .meta.lastUpdated

      <comment value="For many bundles, the timestamp is equal to .meta.lastUpdated, because they are not stored
       (e.g. search results). When a bundle is placed in a persistent store, .meta.lastUpdated
       will be usually be changed by the server. When the bundle is a message, a middleware agent
       altering the message (even if not stored) SHOULD update .meta.lastUpdated. .timestamp
       is used to track the original time of the Bundle, and SHOULD be populated.  

Usage:

* document : the date the document was created. Note: the composition may predate the
       document, or be associated with multiple documents. The date of the composition - the
       authoring time - may be earlier than the document assembly time
* message : the date that the content of the message was assembled. This date is not changed
       by middleware engines unless they add additional data that changes the meaning of the
       time of the message
* history : the date that the history was assembled. This time would be used as the _since
       time to ask for subsequent updates
* searchset : the time that the search set was assembled. Note that different pages MAY
       have different timestamps but need not. Having different timestamps does not imply that
       subsequent pages will represent or include changes made since the initial query
* transaction | transaction-response | batch | batch-response | collection : no particular
       assigned meaning

The timestamp value should be greater than the lastUpdated and other timestamps in the
       resources in the bundle, and it should be equal or earlier than the .meta.lastUpdated
