I'm not sure if my response leads to an opinion on your question and what that opinion might turn out to be. But my issue is this: when the resource is not expressed as a serialization but something with more complex structure of which a substructure is to be selected, it is unclear whether either of these models is adequate. A simple example might be that the target of an Annotation is a Google BigTable and the fragment is given by a row key and six column keys. Simpler might be a special case of a spreadsheet with column and row headers, and a corresponding fragment based on those headers . Even if the spreadsheet resource were serialized, e.g. as CSV, I might still wish to make assertions about this data object independent of the column and row ordering. With annotation of data objects, my intuition is that anything that even smells of a linearized selection imposes consequential requirements on the dereferencing of the selection should that be necessary.
