I think that's more on the developers than the spec, many of whom are
shakey on the sequence concept, too.  It's not hard to find out what a
path step is or how it's defined, certainly not with the current
specifications.

XSLT 2.0 was some time ago now, but I don't recall that I had to read
the specification closely -- or at all -- to find out that
//*[not(*)]/name() worked.  It was probably this list.

Teaching is not a spec task; neither are publicity or communicating best
practices.
