Bob,

A desired feature that led to the current rdf:List structure is the ability to 
"close" a list - so some separate sub-graph can't "silently" add properties not 
in the original.  Your pattern might allow this through additon of a 
"maxSlotIndex" property on "olo:OrderedList" (not suggesting this as a design, 
just an example).
