All good advice.

Slightly flawed (unless you are using the old MSMXL ??).  It doesn't
matter where you put this template, because the default priority for a
name pattern like 'book' is higher than for qualified patterns like
'book[@...]'.  But rather than rely on default priorities, a nice
trick I saw somewhere else (in schematron?) is to give this template a
priority of -1.  You are then guaranteed it will not be chosen in
preference to anything else, whatever the style of pattern.
