[Moims-ipr] CESG Final Review of XFDU Structure and Construction Rules

[Nestor.Peccia at esa.int]

Peter,

Looking at the figures, the real problem is the Figure 11-1.

Figures 4.1 to 4-6, 5.1, 6.1, 7.1, 8.1, 9.1 are a subset of Figure 11.1. They
are readable.

Steve /Dan have sent us the following diagrams, which I believe solve the
problem

(See attached file: schema size.doc)(See attached file:
xfduexpanded_nobytestreamex.jpg)(See attached file: xfdufullexpand.jpg)

Fig 11.1 in the current BB has the byte stream not expanded.

The above figures (in word and jpg format)  cover both cases
- expanded with nobyte stream
- full expanded

I have copied Tom as well, because I believe it is an editorial issue (if the
current quality is accepted). Personally I have printed the figures in a
normal network printer, and I can read them.

ciao
nestor

Nestor,

We provided feedback to the CCSDS Secretariat directly and did not
copy you.  Sorry for the oversight.  I thought that they would have
responded by now, but what follows is the essence of it.

Regards, Peter
