After the e-mail thread resulting from my initial proposal[1] for
closing Issue 302[2] I thought it might be useful to update the proposal
based on the feedback. Here goes;

From the ensuing discussion it seems that people are happy with;

	2. Amend clause 4 of[5] to read:

	Certain graphs may sometimes contain a given edge and at other
	times that edge will be missing. Such missing edges can either
	omitted from the 	serialization or can be encoded as an
	information item with an xsi:nil attribute information item
whose value
	is "true". 

The above effectively covers ( or makes unnecessary ) the 'outbound
only' case

We still need to tackle the 'inbound only' case. Noah is correct in[3]
when he draws a graph with an inbound only edge. This is one way to tell
the story and one I am perfectly happy with.

The other way would be to state that encodings start with a node rather
than an edge. This would require us to modify the language concerning
EIIs and whether they represent edges, nodes or both. Currently EIIs
always represent an edge and may also represent a node. We would need to
add a case where an EII represented just a node. This would mean
re-writing 3.1.1[4] and at the moment I'm struggling to come up with a
reasonable and concise formulation. 

Thus unless anyone STRONGLY objects to the notion of an inbound only
edge, I suggest we leave in the text about 'An edge MAY have only a
terminating graph node, that is be inbound only.' in the current
edcopy[6]. Remove the text about 'outbound only' edges from [6] and
amend clause 4 of[5] as described above.
