Interesting that RELAX NG, like XML Schema, requires a restricted type to
spell out all the components that are to be included in the subtype, rather
than inheriting them by default: which is something of a maintenance
nightmare. I've always wondered why XML Schema is asymmetric here as regards
elements vs attributes: with attributes you say which ones to leave out of
the subtype, with elements you say which ones to include.
