[jlreq] Example of central-baseline alignment of sideways-ed Latin glyphs within a vertical Japanese line box (#246)

TalbotG has just created a new issue for https://github.com/w3c/jlreq:

== Example of central-baseline alignment of sideways-ed Latin glyphs within a vertical Japanese line box ==
Dear fellow jlreq colleagues,

In section 2.3.2
https://www.w3.org/TR/jlreq/#major_differences_between_vertical_writing_mode_and_horizontal_writing_mode
I believe there ought to be an example of central-baseline alignment of sideways-ed Latin glyphs within a vertical Japanese line box . Why?

- because very few people actually know that sideways-ed Latin glyphs within a vertical Japanese line box ('writing-mode: vertical-rl') must be central-baseline aligned
- because very few web authors actually know about this
- because there is no known tutorial on CSS writing-mode out there on the web that actually states this
- because the current - today - CSS Writing Mode spec
https://www.w3.org/TR/css-writing-modes-3/
does not have an example of this and because 
its statement
"
In vertical typographic mode, the central baseline is used as the dominant baseline when text-orientation is mixed 
"
is actually understood by few (technical-advanced) people like ourselves

Please note that the current version of "Requirements for Japanese Text Layout" does not use the word "baseline" anywhere. Not even once, in the whole document!

Thank you for your understanding,

Gérard
