19.147: draw:escape-direction, unable to arbitrarily combinedirections

draw:escape-direction is currently specified as *one* of auto, left,
right, up, down, horizontal or vertical.

a) There isn't the capacity to describe a a gluepoint with a combination
of escape directions, e.g. left+up

As an aside, this is something possible to select in OpenOffice.org's UI
and works correctly, but cannot be saved to ODF.

b) "auto" is specified as "the connection line may leave in all four
directions from a drawing object". Is this entirely correct and/or
intended ? i.e. in practice OpenOffice.org uses "auto" to mean that "the
connection line may leave in all four directions, but will be
auto-routed to the glue point, avoiding drawing over other shapes if
possible.
