In WACZ Signing and Verification section [4.1.1](https://specs.webrecorder.net/wacz-auth/0.1.0/#anonymous-signature), the [text under the example](https://github.com/webrecorder/specs/blob/main/wacz-auth/0.1.0/index.html#L208-209) reads: > With this approach, the WACZ contains just enough to validate that they signature with the publicKey. This reads like it's missing a word, could it be clarified?
