<div>My proposal from last June – see below – addressed a couple of issues related to the ongoing discussions on sharing tables in a Font Collection.</div>
<div><br>
</div>
<div>– It doesn’t look like the name ID 6 item made it into the latest OT spec: <a href="http://www.microsoft.com/typography/otspec/name.htm">
http://www.microsoft.com/typography/otspec/name.htm</a> </div>
<div>– the hmtx item, however, did: <a href="http://www.microsoft.com/typography/otspec/hmtx.htm">
http://www.microsoft.com/typography/otspec/hmtx.htm</a></div>
<div><br>
</div>
<div>Vlad & Michelle, if you could help untangle this, I’d appreciate it. I should have kept track of this more closely; sorry about that.</div>
<div><br>
</div>
<div>Thanks,</div>

the whole description is going to be modified and the sentence you want to delete will just be moved with the rest of the text to the Recommendation section. Would you rather have it removed from the Recommendations as well?<o:p></o:p></span></p>

them to be reviewed by the AHG members. I would consider this for the next round of ballot comments.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size: 10.5pt; font-family: Calibri, sans-serif; color: black;">[proposed replacement:] An OpenType engine must use the advanceWidths in the hmtx table for the advances of a CFF OpenType font, even though the CFF table
specifies its own glyph widths. Note that fonts in a Font Collection which share a CFF may specify different advanceWidths in their hmtx table for a particular glyph index.<o:p></o:p></span></p>
