/**
* SECTION:gstchildproxy
* @short_description: Interface for multi child elements.
* @see_also: #GstBin
*
* This interface abstracts handling of property sets for child elements.
* Imagine elements such as mixers or polyphonic generators. They all have
* multiple #GstPads or some kind of voice objects. The element acts as a parent
* for those child objects. Each child has the same properties.
*
* By implementing this interface the child properties can be accessed from the
* parent element by using gst_child_proxy_get() and gst_child_proxy_set().
*
* Property names are written as "child-name::property-name". The whole naming
* scheme is recursive. Thus "child1::child2::property" is valid too, if
* "child1" also implements the #GstChildProxy interface.
