<p>The previous draft of the "New feature variations" document is
attached. The sections on the specific implementation in this
draft are now out of date -- refer to the newer draft for those
specifics. However, this earlier draft also has the explanatory
material referenced in the last meeting, particularly concerning
the scaling problems with the current system and a specific
example comparison of the two. <br>
</p>
<p>Now, on DMAP and the lack of specifics about other formats ...<br>
</p>
<p>Just as a starting point for discussion, suppose the convention
was:</p>
<ol>
<li>Formats 4, 12, ? work as described in the current draft</li>
<li>For all other formats, if there is a cmap subtable of that
format but no DMAP, the cmap table is used and any implicit or
explicit references to other formats refer only to the content
in cmap, never to dmapl<br>
<br>
If there are cmap and DMAP subtables of that format, or just a
DMAP subtable, the DMAP subtable is used and the cmap table (if
any) is ignored. Any implicit or explicit references to other
formats are to the DMAP table (if not format 4, 12, ?) or to the
combination of the DMAP and cmap tables (if format 4, 12, ?). <br>
</li>
</ol>
<p>This is a relatively simple convention and probably fine for any
subtable format not likely to be large. So: would people be happy
with this, or are there other formats likely to be large enough to
optimize for, and how should sharing be defined for those?</p>
