Re: [csswg-drafts] [css-inline-3] Naming Stuff (#8067)

I have a very basic understanding of the terms used in typography. Though the specification defines different types of "baselines" for different writing systems. And it defines the word "baseline" as the line along which individual glyphs of text are aligned. According to the spec., the "alphabetic baseline" is used in Latin, Cyrillic, Greek and other scripts, while the "hanging baseline" is used in Tibetan. There is also an "ideographic central baseline" which is halfway between the "ideographic-under baseline" and "ideographic-over baseline".

As I understand you, your claim is that the specification misuses term "baseline" as the line used for alignment and "baseline" _only_ refers to the a specific line somewhere at the bottom of the characters. And there is no such thing as an "alphabetic baseline", "hanging baseline" or a "central baseline" in the terminology of typography. Writing systems that use the hanging line to align their characters still have a baseline somewhere at the bottom of the characters. Though that baseline is unrelated to character alignment.
Does that summarize your concerns correctly?
