Here's an example that I've encountered more than
once:

<foo>
    <value>20010312T143213</value>
</foo>

For the sender, the value element contains a batch ID
that uniquely identifies a batch of transactions.
The sender happens to use a timestamp as the batch ID,
even though the value element may contain any
string that uniquely identifies the batch.

For the receiver, the value element contains the
date and time when the message was created. The
receiver is not interested in batch IDs, but is
interested in the creation date and time.

Best regards,

Bob
