In my view, only the first syntax sould be allowed.
For instance, in real world protocols are nested (Ethernet includes IP that includes TCP...).
However, when you display such a packet on the screen, you should display it as:

    ethernet
       field1
       field2
       ....
    IP
       field1
       ....

So, it is much easier not to have nested <proto> tags, since this is not what you want in the output.
This is how PDML has been defined so far.
Just my idea, obviously.
