You are using HTTP accept-parameters in a context where a media type
with optional parameters is expected; in other words, this is non-
compliant at the moment since there is no 'q' parameter for the type.

If you read the definition of the media atteribute, you'll find that it
has a dual nature, specifically, it can describe "for which media the
document in question was designed". While this is not currently the case
for 'icon', it could easily be made so, and if, the above would mean the
icon was designed for a viewport or page box of at most 16x16px. If the
icon is rendered into a 16x16px viewport, well, I'd find that fitting.
