SimpleSign Inline Mode and Base64

In http://wiki.oasis-open.org/xri/XrdOne/SimpleSign, I have changed the name 
"Wrapped mode" to "Inline Mode" since I dropped the wrapper.

Now, it is like George suggested.

<XRD sig="signature" sigalg="http://www.w3.org/2000/09/xmldsig#rsa-sha1" 
certuri="pem file location" data="BASE64 of the payload" />

When I was talking about this with Masaki, he suggested that since BASE64 
usually
wraps at 76 or less characters per line, doing it like:


<XRD sig="signature" sigalg="http://www.w3.org/2000/09/xmldsig#rsa-sha1" 
certuri="pem file location" mode="inline">

Which do you think is better?

Any opinion?
