+The filter function receives a single object of type `ProcessInfo`
 which has with three members:
 
- * `place`: read-only information about the place being processed.
+ * `place: PlaceInfo`: read-only information about the place being processed.
    See PlaceInfo below.
- * `names`: The current list of names for the place. Each name is a

- * `address`: The current list of address names for the place. Each name
-   is a PlaceName object.
+ * `names: List[PlaceName]`: The current list of names for the place.
+ * `address: List[PlaceName]`: The current list of address names for the place.
 
 While the `place` member is provided for information only, the `names` and
 `address` lists are meant to be manipulated by the sanitizer. It may add and
 remove entries, change information within a single entry (for example by
 adding extra attributes) or completely replace the list with a different one.

 The filter function first checks if the object is interesting for the

 Save the source code in a file in your project directory, for example as
 `us_streets.py`. Then you can use the sanitizer in your `icu_tokenizer.yaml`:

     This example is just a simplified show case on how to create a sanitizer.

 ## Custom token analysis module

-analyser factory. A token analysis module must therefore implement two
