If the distinction is to be based on outline type, then I think <br>
'font-ttf' and 'font-cff' is much preferable to using 'font-otf' for the <br>
latter. The only reason .otf is not typically used as a file extension <br>
for TrueType fonts is so that the latter are backwards compatible with <br>
older Windows systems that do not recognise .otf; this is obviously less <br>
of a practical concern than it was in 1998, and now persists mostly as <br>
convention. I have, however, seen some TrueType fonts with an .otf <br>
extension.<br>
<br>
OTF stands for OpenType Font, not PostScript OpenType Font, and the <br>
first item in the OpenType catechism is that an OpenType font may <br>
contain either TrueType or PostScript outlines. Hence, I think it is <br>
misleading or at least confusing to identify 'font-otf' with PostScript <br>
outlines.<br>
<br>
I also wonder about using either 'font-off' or 'font-otf' to indicate an <br>
unknown outline type: the former because OFF is not a widely used or <br>
recognised abbreviation -- the Open Font Format being reasonably seen as <br>
a particular publication of the OpenType Font specification --, and the <br>
latter because of potential confusion in the minds of those who, due to <br>
convention, associate .otf with PostScript outlines.<br>
<br>
I wonder if there might be grounds for a generic 'font-sfnt' MIME type, <br>
which would not only express the desired agnosticism regarding outline <br>
type, but would also be useful for fonts containing non-OTL layout tables.<br>
<br>
So we might have:<br>
<br>
application/font-ttf<br>
application/font-cff<br>
application/font-sfnt<br>
