Erm... the document David quoted from is part of the source tree - see
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libshell/common/COMPATIBILITY
(and I#ve uploaded a copy with the general ksh93s+ documentation on the
ksh93-integration project homepage at
http://www.opensolaris.org/os/project/ksh93-integration/docs/ksh93s/general/compatibility/).
