I'd say it depends on how you frame the requirement. If
it's "include a link
to a thumbnail",  then you're probably right, there
isn't a universal
solution.  But I think  "include a link to a
thumbnail" is too narrow a
requirement.   I believe that a library/metadata perspective
would suggest
generalizing the requirement  to "include an
indication of what a link
accesses", the "indication" being a term
from a controlled vocabulary (which
would include "thumbnail").

In other words, add an optional attribute to <link>,
for example, <link
access="thumbnail">.

This, I feel safe to say, would be the approach favored by
the digital
library/metadata community. It is the approach taken with
the MODS metadata
initiative (see http://www.loc.gov
/standards/mods/).   MODS defines such an
attribute, "access", and there is a starter
vocabulary, not yet
well-developed, but the Library of Congress is committed to
supporting and
maintaining a controlled vocabulary for this purpose.   So
you could say:

<link mods:access="thumbnail">
