Benoit,

> I was initially confused by that sentence.

My understanding is that "independent characteristics" applies on a tag-by-tag basis.  I might suggest:

	Each tag carried by the administrative tag TLV SHOULD be used to
	indicate a characteristic of a node that is independent of the
	characteristics indicated by other administrative tags.
<Shraddha> Thanks for the text. Updating -08 version with above text.

Thanks,
--David
