I like border-pattern. It's a little longer than border-parts, but it
avoids the plural.

Any other opinions on this?

It should probably be the same as for the margin properties:

  Percentages: 	width* of containing block
  *) if the containing block is horizontal, otherwise the height

This could work. Then we could do:

  border-pattern: on(4em) off(1em) off(1fr) on(4em)

instead of the more cryptic:

  border-pattern: 4em 1em 0 1fr 4em

But this is still shorter, and quite readable actually, so I think we
should keep it.

These clip regions would be rectangular, right?
