Personal response:

I'm not sure I understand why this should be the case. Most characters that are
metacharacters when used outside square brackets (for example "+", "?", "(")
are allowed with their ordinary meaning (that is, to represent themselves)
inside square brackets. If you can write "[+-Z]" then it's not clear to me why
you shouldn't write "[$-Z]". The case of "^" is a bit more complex, because it
has a special meaning inside square brackets that it doesn't have outside. But
the XPath regex syntax is not changing its meaning inside square brackets, it
is only changing its meaning outside.
