Point taken. However, the diagnostic could be more insightful as to
suggest that the variable usage itself is wrong. Now the message reads
like the match pattern is OK, but the processor fails to see the
variable definition. Combined with non-intuitiveness of the "variable
references are forbidden in a match" rule, and the fact that some
popular processors including libxslt itself used to overlook it, it can
lead to confusion on behalf of inexperienced users (like me).
