<p class="MsoNormal">As yet, a WG with defined scope has not yet been formed. But here’s my inclination:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">1. Lack of font metrics for writing systems other than Western & CJK:
<o:p></o:p></p>
<p class="MsoNormal">yes<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">2. Italic / Oblique Default Angle<o:p></o:p></p>
<p class="MsoNormal">IMO, the CSS WG doc doesn’t make clear what problem is to be solved. Until the problem is clarified, it should be out of scope for any WG.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">3. Compatibility problem with 'vert'<o:p></o:p></p>
<p class="MsoNormal">I think so.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">4. Clarifications for 'vert'<o:p></o:p></p>
<p class="MsoNormal">I think so.<o:p></o:p></p>
<p class="MsoNormal">(Is this really different from 3?)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">5. Clarifications for Bopomofo<o:p></o:p></p>
<p class="MsoNormal">I don’t see a problem here. If tone marks require special positioning, OpenType already provide mechanisms for that. What’s missing?<o:p></o:p></p>
<p class="MsoNormal">If what is missing is documentation to help implementers know what is needed to support a script, then that might be in scope.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">6. Cursive elongation<o:p></o:p></p>
<p class="MsoNormal">Probably<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">7. Fidelity of Font Metrics<br>
Not sure / probably not: this sounds like more of an education problem than a specification problem, unless there are points on which spec’s could be made clearer.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">8. Required vs Optional Ligatures<br>
Same as for 7.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">9. Overline Metrics<br>
Not sure: it’s unclear whether scope for a “shaping” WG should include something like specifying new OpenType table formats that add new metric values unrelated to shaping.<o:p></o:p></p>
