Neat idea.

You're not the first to identify the need for a "serial subset" of XPath, by
which I basically mean a pattern that can be evaluated against a node
knowing only the attributes, ancestors, and attributes of ancestors of that
node. In fact, back in the days when Saxon was a serial SAX-based
transformer, I had a rather similar subset myself! XML Schema now uses a
rather smaller "serial subset" than yours.
