     10 BUILD Type(Name)
     11 This comment signals that a node of type <Type> is created with the
     12 name <Name>.

     14 ERROR Error String
     15 This comment signals that a error of <Error String> is generated.  The error
     16 is not assigned to a node, but are expected in order.

     19 This comment signals that a property has been set on the Node such that
     20 <Key> = <Value>.
