I also recommend avoiding having link relations have *different*
effects on <a>/<area> and <link>.

Agreed.

In that case, I would prefer to have two columns:

"effect"

and

"allowed on"


This has a few advantages over the current "Effect on link" and
"Effect on a, area" split:

1. It encourages the same effect on all elements that the link
relation is allowed on.

2. The "allowed on" column can be simpler and perhaps automatically
used to extract validation/linting hints.

3. The "allowed on" column better allows for expressing other elements
(or vocabularies?) that may use rel.


Ian - do you have any objections to using "effect" and "allowed on"
rather than  "Effect on link" and "Effect on a, area"?

If not, I'll go ahead and add these columns to the microformats
existing-rel-values page accordingly.

Thanks,

Tantek
