7.17.4 "text-decoration"

CSS2 Definition:
Value:  none | [ [ underline | no-underline] || [ overline |
no-overline ] || [ line-through | no-line-through ] || [ blink |
no-blink ] ] | inherit


When converted (laboriously) to a schema definition...
It is long.
It is (to me) largely incomprehensible. I asked and received help from
the rng list.

There are a few examples of this...
I wonder
a) if xsd 1.1 can cope any better
b) this complexity is needed.
c) If it is needed, could it be simplified in some way
