 ### Function-only attributes
 
-- `macro_registrar` - when using loadable syntax extensions, mark this
-  function as the registration point for the current crate's syntax
-  extensions.
+- `plugin_registrar` - mark this function as the registration point for
+  compiler plugins, such as loadable syntax extensions.
 - `main` - indicates that this function should be passed to the entry point,
   rather than the function in the crate root named `main`.
 - `start` - indicates that this function should be used as the entry point,
