>>> bpy.types.Scene.coll = bpy.props.CollectionProperty(bpy.types.PropertyGroup)

Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
TypeError: Required argument 'attr' (pos 1) not found

Docs:

CollectionProperty(items, type="", description="", options={'ANIMATABLE'})

There is no "items" in fact, and the keyword argument for type uses "type " as key, not "attr".

This whole props doc needs cleanup ;)

Will commit a cleanup of doc of props (many things were missing, and a few ones were wrong). Please note though that it won't 'fix' exactly that report, there is some complex python magic here, and all the props funcs do have a first 'attr' parameter.

That’s why all parameters to these funcs must be passed as keywords!
