I fail to see an example in the proposal (other than a layout
of the dominoes as played, which I do not consider to be
a plain text use) where there is a semantic distinction between
orientations. There are examples in Figures 4 and 5 where
an orientation has been chosen for stylistic reasons. However,
those stylistic reasons can be accommodated without having
to encode all four orientations of each bone, by picking a
standard orientation for the unstyled bone.
