I agree it's more important.

where does "structural markup" stop and "metadata" start is the 
issue: what's data to one application is meta to another.

how about the example of attributes added to table to allow for better 
navigation: this is within a page.

also agreed to the extent that one (LINK) is a much simpler way of
doing something the other supports (or will) more exhaustively.

yeah, but that's really a last resort hack (to paliate poor xml
include facilities in html) and shouldn't be used as an argument
