I think as I said, provide a untaint tool, that allows custom data to verify

Like:
${untaint(${var},

No; this is a bad idea.

It is far to easy for someone to write a matcher which just
untaints everything, disabling the security.  Three people
would do that, and one would post it on serverfault.  Then
it would be cargo-culted forever.
