+			sent as CFDataRef instances to the OUTPUT attribute of the
+			transform.
+				
+			This transform recognizes the following additional attributes
+			that can be used to modify its behavior:
+				
+			MAX_READSIZE (expects CFNumber):  changes the maximum number of
+			bytes the transform will attempt to read from the stream.  Note
+			that the transform may deliver fewer bytes than this depending
+			on the stream being used.
