You are totally correct.. In my experience I generally don't see a submit input item with a name attribute unless the coder is interested in the value of the submit button..

<input type='submit' name='submit' value='Next'>
<input type='submit' name='submit' value='Previous'>

Of course you can make it whatever name you want, but if you don't particularly care what submit button they hit, just don't provide a name attribute:

<input type='submit' value='Save'>
