Many thanks to everyone! I think this will get us to AC review in time
for a F2F at the Technical Plenary.

For posterity's sake, below is an accounting of how these were
implemented in the charter:

+        <li><p><b>Semantics</b>, possibly defined as SPARQL operations, specifying how shapes are evaluated against RDF graphs.</p></li>

-      <p>The WG <strong>MAY</strong> produce a Recommendation for <strong>graph normalization</strong>.</p>

~        <li><p><strong>OPTIONAL</strong> - <b>Compact, human-readable, non-RDF syntax</b> for expressing constraints on RDF graph patterns (aka shapes), suitable for the use cases determined by the group.</p></li>
-   This syntax might be a variation of an existing standard, such as templates for SPARQL, or something new, such as ShExC.

no change

no change


I also added ", with some extensibility mechanism for complex use cases." to the first deliverable. I presume this is non-controversial.

There are subtle nuances encoded in font variation and clever layout
which can only be seen by printing this message on high-clay paper.
