//
// in XmlPublishedCache, IPublishedContent instances are not meant to survive longer
// that a request or else we cannot guarantee that the converted property values will
// be properly managed - because XmlPublishedProperty just stores the result of the
// conversion locally.
//
// in DrippingPublishedCache, IPublishedContent instances are meant to survive for as
// long as the content itself has not been modified, and the property respects the
// converter's indication ie whether the converted value should be cached at
// .Content - cache until the content changes
// .ContentCache - cache until any content changes
// .Request - cache for the current request
//
// a fragment can be either "detached" or "managed".
// detached: created from code, managed by code, converted property values are
// cached within the fragment itself for as long as the fragment lives
// managed: created from a property converter as part of a content, managed by
// the cache, converted property values can be cached...
//
// XmlPublishedCache: same as content properties, store the result of the
// conversion locally, neither content nor fragments should survive longer
// than a request
// DrippingPublishedCache: depends
// .Content: cache within the fragment
// .ContentCache, .Request: cache within the cache
//
// in the latter case, use a fragment-owned guid as the cache key. because we
// don't really have any other choice. this opens potential memory leaks: if the
// fragment is re-created on each request and has a property that caches its
// converted value at .ContentCache level then we'll flood that cache with data
// that's never removed (as long as no content is edited).
//
// so a requirement should be that any converter that creates fragment, should
// be marked .Content -- and nothing else
