Currently a wiki page can only be reference once by
any/all structures. There is no reason why structures
couldnt be more flexible, allowing a page to be
referenced many times from within the same structure or
by multiple structures.
Before this is fixed however, it would be nice if Wiki
Pages were first modified to allow referencing by an ID
as apposed to their WikiName. Not sure if there is a
Bug/RFE already open for this?
