Umm...  I mean, I know about that rule, but there is no @property in this
instance.  There is an implicit @about on <head>, and there is a <link
rel="stylesheet" href="somepath.css"> - this should generate a triple <>
xv:stylesheet http://whatever.domain/somepath.css .

Well - stylesheet might not be a good example, since in HTML5 there are
only a few reserved terms.  I might not be thinking about this completely
clearly.
