When is the next opportunity for registering new features?
I ask, because I may have a couple in the proverbial
hopper:<br>

From that discussion paper:<br>
<br>
'Our meeting ended with lunch at PHB, along with the idea to
register two new OpenType <br>
GPOS (Glyph Positioning) features that would be tentatively
tagged 'cspc' (“Contextual <br>
Spacing”) and 'vcsp' (“Vertical Contextual Spacing”), and which
would behave like the 'kern' <br>
and 'vkrn' in that they adjust inter-glyph spacing.<br>
...<br>
'In order to be able to test in environments that do not support
arbitrary OpenType <br>
features, the example font includes the lookups for the 'cspc'
and 'vcsp' GPOS features <br>
in the 'kern' and 'vkrn' GPOS features, respectively.'<br>
<br>
Can you explain why you want to register two new features for this,
rather than just putting the lookups in the 'kern' and 'vkrn'
features as in this demonstration?<br>
