Actually, as a pattern it seems to mean different things depending which
explanation you read. Arguably the sentence below production [52] "A pattern
is defined to match a node..." is definitive, in which case by definition
the pattern means the same thing in both contexts. If this is true, however,
the "it is easy to understand" explanation that follows appears to be
incorrect.
