1. In the mapping rules for notation 3.12.2

{public identifier} The ·actual value· of the public [attribute] 

Since "public" is now optional, shouldn't the above rule be changed to 
something similar to "system"?

{system identifier} The ·actual value· of the system [attribute], if present, 
otherwise ·absent·. 

2. In the description of the properties 3.12.1

{system identifier}
Optional if {public identifier} is present...
{public identifier}
Optional if {system identifier} is present...

So it seems that at least one of "public" and "system" attributes must be 
present in the schema document. This may warrant a clause in "Notation 
Definition Representation OK".
