First order of business was to consider scope. It looks like the majority of changes are clarifications, enhancements, and possible additions to the existing HAnim 2.0 standard without requiring major architectural changes. Thus our consideration of these
changes is proceeding with the expectation that these are enhancements to HAnim 2, namely v2.1 Draft, and not a hypothetical version 3.0.</div>

As mentioned and minuted in the recent HAnim meeting, Carol has made it pretty easy to review proposed changes. She has copied each HAnim specification clause into Google Docs files and applied markup for suggested additions/deletions as shown above. Using
that document link (see top of Mantis issue), we are considering prose carefully as we transcribe and edit the draft specification using HTML.</div>

We plan to continue working through Carol's many suggestions each week. We will provide occasional updates on draft modifications that seem salient, so that HAnim and X3D working groups can review. Anything that doesn't "make the cut" gets listed in Mantis,
and reported on the HAnim mailing list, for further consideration and improvement. Thus we remain fully committed to consensus-based improvements within the proven-successful Web3D process.</div>

A second major review point holding especial appeal is that it appears we can align more closely with IEEE 3D Body Processing (3DBP) standards progress. This has potential to be a great achievement.</div>
