An end-of-packet condition while reading any aspect of a floor 1
-configuration during setup renders a stream undecodable. In
-addition, a \varname{[floor1_class_masterbooks]} or
+configuration during setup renders a stream undecodable. In addition,
+a \varname{[floor1_class_masterbooks]} or
\varname{[floor1_subclass_books]} scalar element greater than the
highest numbered codebook configured in this stream is an error
-condition that renders the stream undecodable.
+condition that renders the stream undecodable. All vector
