Can't we just use the usual last-setting-wins,
ignore-properties-with-unrecognizable-value rules for that?

I am opposed to changes that introduce new places where you don't have
to put quotation marks around a URL, as each such place requires
special-casing in the grammar.  (Also, "," can legitimately appear in
a URL.) Either of

 sprite(<string>, ...)
 sprite(<uri>, ...)

would be fine, with <string> my preference to minimize typing.
