[css-counter-styles-3] Korean hangul informal counting style?

[c933103]

In https://drafts.csswg.org/css-counter-styles/ , numerous complex counting styles including a few for CJK languages have been defined. One of the counting style is korean-hangul-formal which is writing the numbers out in Korean Hangul.
However, according to the first reply in w3c/klreq#22 , there is an informal variant of the counting style that is also seen in Korean text, which omit the leading 일 for some numbers when the condition is met.
I think it would be a good idea to include the style into the specification, especially given that the complexity of the algorithm it seems like it is more suitable to add it in the css-counter-styles-3 instead of predefined-counter-styles

https://www.w3.org/TR/predefined-counter-styles/ contains korean-hanja-informal, and korean-hangul-informal would be the Hangul counterpart of that style.

Could you provide more details on the precise numbering schemes being proposed? It looks like the klreq thread has at least four suggested styles, and none of them provide enough detail currently for me (a Hangul liker-but-amateur) to produce a correct counter algorithm.

I'm not sure which are four suggested styles as I only see two there, but I think the syllable and consonant styles in https://w3c.github.io/predefined-counter-styles/#korean-styles are all more usual and frequent in real world than korean-hangul-formal.

To list:

• circled-korean-consonant
• circled-korean-syllable
• hangul/korean-syllable (alias?) - This is the most frequent one I think, but I have no data to support that)
• hangul-consonant/korean-consonant (alias?)
• parenthesized-hangul-consonant
• parenthesized-hangul-syllable

The below is a screenshot from Hangul (word processor) which supports hangul/parenthesized-hangul-syllable/parenthesized-hangul-consonant from the above list, while no support for korean-hangul-formal. (Ignore the red arrow.)

This is from Microsoft Word, you see hangul at the center of the list.
