No, it's not.  There is currently no way to symbolize roads using standard
highway symbols in xastir.

If you set "symbol" in a dbfawk rule, it allows a point feature (and only
a point feature) to be symbolized by standard APRS symbols like the ones
you can give to your station or to objects/items.  Table, ID and overlay
are the character's you'd transmit in your posit (e.g. "/- " for a house,
or "\#S" for a new n-N paradigm digipeater).

That field is typically used when you generate hand-rolled point shapefiles
and want to symbolize them somehow (see README.MAPS for an example of how
to do it).
