3 tiny issues.

1-
https://www.w3.org/TR/2019/CR-css-writing-modes-3-20190903/images/orthogonal.svg
used in Example 11 of section 7.3 Orthogonal Flows

"extent" and "measure" are not defined anywhere; these are remainings of 
older versions.
"measure" should be replaced by "inline size".
"extent" should be replaced by "block size".

2-
In an ideal version of the spec, colors of arrows would be consistent 
across sections and reused in all examples.
So, blue would be for glyph orientation (pointing toward ascender side 
or "top" side of a line box),
orange for inline flow and green for block flow.

3-
In
https://www.w3.org/TR/2019/CR-css-writing-modes-3-20190903/#fig-text-orientation
in section 5.1 after definition of sideways:
the images are horizontally offset a bit from their terms. If I toggle 
off
.figure img {display: block;}
then the images are correctly aligned with their terms.
