Depending on what Rob thinks, it might make sense to remove the above
two "REQUIRED" bits.  That would match his earlier feedback since
we're still in the "Required" section and thus it is redundant.

I'd second what Doug said wrt. the removal of the unnecessary "REQUIRED" 
statements of the clock names, especially as the surrounding text makes that 
requirement pretty clear.

Otherwiese looks nice, so
