 	There are 4 clipboard permissions:
 
-	* { name: "clipboard-read", allowWithoutGesture: false }
-	* { name: "clipboard-read", allowWithoutGesture: true }
 	* { name: "clipboard-write", allowWithoutGesture: false }
 	* { name: "clipboard-write", allowWithoutGesture: true }
 
 	With the following relationships:
 
-	* <code>{ "clipboard-read" + true }</code> is stronger than <code>{ "clipboard-read" + false }</code>
 	* <code>{ "clipboard-write" + true }</code> is stronger than <code>{ "clipboard-write" + false }</code>
 
-	Note: "clipboard-read" and "clipboard-write" are two separate permissions with no
-	inherent strength relationship. However, user agents MAY choose to impose such a
-	strength ordering on these permissions, for example by making the "clipboard-read"
-	permission act stronger than the "clipboard-write" permission. Doing this would
-	effectively turn the "clipboad-read" permission into a way to provide full
-	read/write access to the clipboard since granting (or denying) "clipboard-read" would
-	also grant (deny) "clipboard-write" access.
-
 	While user agents MUST support the {{ClipboardPermissionDescriptor}} as described
 	in this specification, they, of course, retain complete control over the default
 	settings and how (or if) they are exposed to the user.
