-- An interface whereby an object allows its backing content to be
-- streamed to clients.  Typical implementors would be images or
-- icons, HTML content, or multimedia display\/rendering widgets.
-- 
-- Negotiation of content type is allowed. Clients may examine the
-- backing data and transform, convert, or parse the content in order
-- to present it in an alternate form to end-users.
-- 
-- The AtkStreamableContent interface is particularly useful for
-- saving, printing, or post-processing entire documents, or for
-- persisting alternate views of a document. If document content
-- itself is being serialized, stored, or converted, then use of the
-- AtkStreamableContent interface can help address performance
-- issues. Unlike most ATK interfaces, this interface is not strongly
-- tied to the current user-agent view of the a particular document,
-- but may in some cases give access to the underlying model data.
