One should not go so far. Relax NG is not that bad.

hl=("hide"|"show")?
ed=("enable"|"disable")?
lr=("raise"|"lower")?

state=attribute state {list {
    (hl,((ed,lr)|(lr,ed)))
  | (lr,((hl,ed)|(ed,hl)))
  | (ed,((hl,lr)|(lr,hl)))}}

start = element test { state }

Choice is allowed. But in general, regular expressions with interleave would help.
