         Dict of 2D shapes elements (circles, polygons, multipolygons).
         Shapes are regions, they can't contain annotation, but they can be annotated by a table.

     Notes
     -----
     The SpatialElements are stored with standard types:
 
-        - images and labels are stored as :class:`xarray.DataArray` or :class:`datatree.DataTree` objects.
+        - images and labels are stored as :class:`xarray.DataArray` or :class:`xarray.DataTree` objects.
         - points are stored as :class:`dask.dataframe.DataFrame` objects.
         - shapes are stored as :class:`geopandas.GeoDataFrame`.
         - the table are stored as :class:`anndata.AnnData` objects,  with the spatial coordinates stored in the obsm
             slot.
 
-    The table can annotate regions (shapes or labels) and can be used to store additional information.
-    Points are not regions but 0-dimensional locations. They can't be annotated by a table, but they can store
-    annotation directly.
+    Tables can annotate SpatialElements (labels, shapes or points) and can be used to store additional
+    information. Points can also store annotations directly, as additional dataframe columns.
