I agree with this interpretation, but it does not explain _why_ attribute order
is explicitly not relevant.
I, like you, just take this as a done deal (recalling the SGML legacy
requirements, plus the fact it doesn't to me seem a big issue ;-)). But if
Xasima Xirohata wants the underlying reason for this choice, then I suspect the
answer lies deep in the origins / design of SGML.
