Thanks for the information. It seems that it does not disappear from the
font, though:

$ otfinfo -f --script=latn.ISL /usr/share/fonts/truetype/ttf-junicode/Junicode-Regular.ttf
 RQD    <unknown feature>
kern    Kerning
lfbd    Left Bounds
mark    Mark Positioning
mkmk    Mark to Mark Positioning
rtbd    Right Bounds
$ showttf /usr/share/fonts/truetype/ttf-junicode/Junicode-Regular.ttf | egrep ' RQD' 
         Feature[0] ' RQD' Offset=92
         Feature Table[0] ' RQD'
$

(This is for Junicode version 0.6.11 from <URL:http://junicode.sf.net/>.) 

The other problem is that this required feature for latn{ISL} is not
applied by XeTeX. Any idea how to debug where the error might be?
