OOPS.  You are absolutely correct.  This was an oversight when I did a
cut-and-paste from my previous document.  The MUST made sense when device
certificates were a standalone document, but you're right that this should
be a SHOULD now that it's integrated into 4880bis.

Would you like an updated patch?  Or just change it in your copy?

Thanks,
