This behavior is actually identical between approaches #1 and #2 -- in both
cases an API would be exposed on the document to select a given style set by
title.  The only question is whether disabled sheets with that title would
become enabled in the process (in approach #1 they would, but not in approach

Mozilla, in fact, implements approach #1, with the exception of a lack of easy
API for selecting a style set.

Good point.

Again, you can select one title in either approach; the only question is what
that does, exactly.

Also a good point.

Possible, but the HTML specification normatively defines the title attribute of
<link> with rel="stylesheet" to have this meaning....

On an interface implemented by the document object.

Such an attribute would need to exist in any case, because switching style sets
is so much faster than enabling/disabling individual sheets (because you can
batch all the sheet munging before reresolving style).
