Canonical Grove Representation.

http://www.ornl.gov/sgml/wg8/docs/n1920/html/clause-A.4.5.html

I point this out, not because I think groves and infosets should be
mainstream topics of conversation for XML technologists, just to
point out that this is old territory in the SGML world.

I thought this stuff was off the deep end for SGML and I certainly
think this stuff is waaay off the deep end for the vast majority of
real world XML applications. I'm a tad horrified to see the PSVI rise
dramatically in prominence.

Its all getting way too complicated you know, mumble, mumble, my
ancient limbs are sore, my eyes are week, scratch, cough,
splutter, mumble, mumble.
