OK, so my next question:  the values of data-* properties are
essentially streams of values (or tokens).  What needs to happen to
come up with a computed value for such a property (prior to
inheritance)?  Most importantly, do data() expressions inside that
stream get evaluated when finding the computed value of a data-*
property (and the result inherited), or are the data() expressions
retained through inheritance and computed at the destination?

In other words, given:

  #one { data-a: blue; data-b: data(a); }
  #two { data-a: fuchsia; color: data(b); }
<div id="one">
  <div id="two"></div>

do you end up with div "two" being blue or fuchsia?
