/** Definition of the interface for a collection of PageContent instances.
@remarks
This class acts as a grouping level for PageContent instances. Rather than
PageContent instances being held in a list directly under Page, which might
be the most obvious solution, this intermediate class is here to allow
the collection of relevant PageContent instances to be modified at runtime
if required. For example, potentially you might want to define Page-level LOD
in which different collections of PageContent are loaded at different times.
