To construct an `add-also-known-as` patch, compose an object as follows:

+1. The object ****MUST**** include an `action` property, and its value ****MUST**** be `add-also-known-as`.
+2. The object ****MUST**** include a `uris` property, and its value ****MUST**** be an array. Each value of the array ***MUST*** be a URI. If the value is not of the correct type, the entire _Patch Action_ ****MUST**** be discarded, without any of it being used to modify the DID's state.
