[MPEG-OTSPEC] [EXTERNAL] WD review and input contribution deadline

Tue Apr 19 06:25:23 CEST 2022

Peter, all,

I am not expecting (and will not be supporting) advancing the 5th edition WD
to CD at this time - there are many other changes that need to be introduced
and discussed, and I agree that the document isn't ready for promotion.

Re renumbering of subclauses of 6.3.3 - while transforming the 4th edition
document to the new ISO House Style I discovered that the final published
version of 4th edition had a bug that caused one subclause to be corrupted,
and there were general inconsistencies with how content was structured. The
current draft reflects changes I made to fix both editorial issues. 

Re: Amd. 1 changes - I believe I introduced all of them exactly as they are
presented, I will have to verify it again - I do have intermediate versions
of the WD document stored after every batch of changes was made (Amd.1,
Amd.1+2, post-Amd.2).

Thank you for conducting a thorough review, really appreciate it.

Vlad

Vlad:

I wasn't expecting to have to review whether this WD accurately reflects
changes in Amds 1 and 2. I'm still reviewing Amd 1 and seeing significant
issues. So, I hope you weren't counting on advancing the WD to CD: it's not
ready!

The subclauses of 6.3.3 appear to have been renumbered. I don't have a
problem with that change, but it's not reflected in the change tracking of
the WD.

Re 6.3.3.3.3 (prev. 6.3.3.2): Amd 1 made a revision to this section by
inserting paragraphs after the first paragraph. However, it did not alter
the first paragraph, nor did Amd 2. So that first paragraph should be as in
the 4th edn. However, in the WD, that first paragraph appears after the
inserted paragraphs and is being deleted. It needs to be restored as the
first paragraph.In 

In 6.4.2: Amd 1 replaced the text of the sixth paragraph. This is not
reflected in the WD.

Further on 5.5.7 - this time I'll review the whole thing before sending.

In Amd 1, the text for example 3 was to have the following inserted:

"The visual result is the same as that shown for Example 2."

That insertion is reflected in the WD.

However, the 4th edition did not include a figure / visual for the second
example. It said, "The diagram is the same as in the above example." (That's
not great wording since it's not clear what is meant by "the diagram".) And
Amd 1 did not insert a figure for example 2.

I suggest that a figure should be added for example 2 for clarity. (This is
what is done in the

the end of example 2:

The following image shows the visual result:

In the text for example 5, there is a typo:

"The following image illustrate visual results."

Change "illustrate" to "illustrates".

For example 7, Amd 1 inserted the following after the code block:

"The following image shows the visual result:"

This is missing from the WD.

Sent too soon:

The remainder of that portion of the changes in Amd 1 also are not
reflected. The second paragraph of 5.5.7 (was 5.5.6) was supposed to be
revised. Change

". an OFF font with SVG glyph outlines."

To 

". an OFF font with SVG glyph descriptions."

It's evident to me now that the changes reflected in the WD do include
changes in Amd 1 and Amd 2.

In Amd 1, the first two paragraphs of 5.5.7 (was 5.5.6) were replaced.
However, the first of those paragraphs is still retained in the WD:

""SVG glyph descriptions must be defined."

The content of that paragraph is redundant: the relevant points are covered
in 5.5.5. That paragraph should be deleted from the WD.

Vlad:

Do the changes shown by change tracking reflect changes in Amd 1 and Amd 2,
or only new changes post Amd 2?
