You could use a 'heavy' polyline, where each vertex is a seperate
database-resident entity that can have xdata attached to them,
but even that may not be a good idea, because user commands
like PEDIT can blow away vertices, and there may be some editing
operations that *appear* like editing, but in fact, are achieved by
replacing existing polylines and vertices with new objects, in which
case, goodbye xdata.
See the PLINETYPE system variable.

Yes of course I can make the lines database persistent but then I lose the reference to the polyline (quasi a parent-child relationship). I would like the lines to leave to be part of the polyline.
