Re: [ogpx] VWRAP Draft Charter: 2009 08 28 revision

Looks like one more find/replace for "OGPX" will be necessary on the text.
:)

Also, I wonder if we should include a note around the "previously published
internet drafts" mentioning that "OGP" was an earlier name used for this
effort, to explain why many of the drafts mention OGP. Meh... probably not
necessary.
