[section Quick Reference]

The following tables use some conventions to encode the attribute type exposed
by a component

[variablelist
    [[`attribute_of(P)`]    [The component exposes the same attribute as the 
                             component 'P' used as part of the overall 
                             construct]]
    [[`value_type(I)`]      [The component exposes the value_type of the 
                             underlying iterator 'I' as its attribute type]]
]
