[MOBY-dev] data by reference - a request for comments

[Mark]

Do you suggest that there is no indication, in the MOBY block, that the  
message contains data-by-reference?  i.e. should our tools simply see that  
the primitive is empty, and then look into the ws header for the  
possibility of a ws-ref, and then if it isn't found, adopt the other  
interpretation of an empty block (i.e. that the data is known to be NULL)

?
