<div dir="ltr">OpenType is designed such that fonts can improve these kinds of things without needing a change to be rolled out to every engine first. We just need one required feature and all kinds of GSUB/GPOS things can be hung onto it. The tags should be reserved for features that are either need to be controlled by shaper, or by user. Everything else should be just one required feature.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Apr 25, 2018 at 1:48 AM, Ken Lunde <a href="mailto:lunde@adobe.com">lunde@adobe.com</a> [mpeg-OTspec] <span dir="ltr"><<a href="mailto:mpeg-OTspec-noreply@yahoogroups.com" target="_blank">mpeg-OTspec-noreply@yahoogroups.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Behdad,

<div>While I see some parallels, the Indic nature of 'dist', along with the fact that a corresponding vertical feature is necessary, makes me think that separate features is better.</div>
<div><br>
</div>
<div>Also, and this is for others, I just noticed that a fair number of OpenType feature tags in the spec are surrounded by smart double quotes, while most are surrounded by single straight quotes. I counted that 16 features have this issue. See the
attached screenshot to see the first three.</div>
