  That's wrong.  Use:

	if (Attribute == ${variable}) {

- Attributes can be referenced just by their name.  There's no need to wrap them in "%{...}".  That is only for other strings.

- wrapping the ${variable} in "" means it will *not* get expanded when the configuration file loads.

  "${variable}" is not supported, and will not be support.
