How should i list your name in the acknowledgements section?

The Unicode document referenced by Ken Lunde's blog above is http://www.unicode.org/L2/L2015/15328-tally-marks.pdf - it refers to four tally styles:

• tally
• box tally
• ideographic tally
• dot-dash tally

"cjk-tally-mark" covers the third, and I don't think that "box tally" and "dot-dash tally" have been encoded in Unicode (yet?). But the first has - for consistency shouldn't it be added as well? It would be

@counter-style tally-mark {
  system: additive;
  additive-symbols: 5 '\1D378', 1 '\1D377'; /* symbols: 5 𝍸, 1 𝍷; */
  suffix: " ";
}

Since we focus on international writing systems, tally-mark seemed a little borderline for this doc, but i have now added it at https://github.com/w3c/predefined-counter-styles/pull/29

Thanks.
