Martin, all,

I went through the issues grouped under the RMA chapter (Chapter 12) and 
found that some of them are issues in the I/O chapter: rows 228-259 
(except for row 239) seem relevant for the I/O chapter and not the RMA 
chapter. I guess there has been some confusion about document and PDF 
numbers. I don't want to mess with the excel sheet but wanted to raise 
this here so that the I/O CC can take a look at these points.
