An example for a reason to increase the
<font style="font-family: Courier New;">
protocol_version
<font style="font-family: Times New Roman;">
is a change to the epoch in clause 4.2.15 and clause 4.2.16, which leads to incompatible messages. A counterexample would be an additional header field using the
<font style="font-family: Courier New;">
unknown
<font style="font-family: Times New Roman;">
case in clause 5.4. This header field can be ignored by old implementations, if the syntax is kept identical and the versions are compatible. Hence, the
<font style="font-family: Courier New;">
protocol_version
<font style="font-family: Times New Roman;">should not be increased.</font>
