"ms" and "rev" attributes in a SOAP response message

[JackyQiu]

In a tipical "getxxx" response message, i.e.
<cn f="" id="299" l="7" md="1148422012" ms="78" rev="78" t="">

What the "ms" and "rev" represent for? For me, they all look like the last token when the item was modified.

[sam]

ms = metadata sequence number
rev = content sequence number (ie, revision number)

if an item's content changes, both get updated to the current mailbox revision number. if an items metadata changes only ms gets updated.

Is this number used to compare with the token number in SyncRequest to return the latest sync data?

The server offers these values; you can use them however you see fit.

You can use them in a SyncRequest. In general, the token you specify in a SyncRequest should be whatever the server returned in the previous SyncResponse.
