<div style="font-size: 14px; font-family: Calibri, sans-serif; ">To put it in perspective, I would say that the 'rclt' feature is a welcome addition for the more complex styles of Arabic writing, but it would not be required for many simple styles. If it's
present in a font, it should not be normally possible to turn it off. By the way, 'rclt' will also be useful to many other scripts which might require more than one pass to refine the final rendered shapes. </div>

<span style="font-size: 10pt; font-family: Georgia, serif; ">“it should not be possible to turn off 'rclt'” is a bit too strong. There are always workflows in which the author may need to turn off even “required” features e.g. when preparing a specimen book

have a consensus approval of the group – we can add them in the draft. After the editing period is over the changes would need to be submitted as input contributions for discussion at the next WG11 meeting so I strongly recommend to consider as much things
done as possible until the end of the month.</span><o></o></p>
