Yes.

VCA_SDU (Virtual Channel Access Service Data Unit).

In any of my restructured books, I made the following distinction:

application data: data provided by the user (in a generic sense). This 
word is only used in explanatory sentences.

Used Data: data contained in a field that is not a header or a 
trailer. This word is only used in sentences that specify data formats.

In the old TC Blue Book, Part 3, this distinction was not strict, so I 
changed the term "Application Data" that appeared in sentences that 
specify data formats to User Data. But this does not mean that I do 
not use the term "application data" at all. In this sense, the list of 
changes that I provided was ambiguous, and I'm sorry for this confusion.

I'd appreciate it if you could make the distinction that I showed 
above in the cross support documents.

What are the protect service and C/VCDU service?
