My bad!  I was attempting to supplement my VERY limited knowledge of basal
avialan taxonomy by consulting Dingus and Rowe, who appear to be rather
confused on several points.

They name the following taxa on page 214:

Maniraptora = {Dromaeosauridae + Neornithes}
Avialae = {_Archaeopteryx_ + Neornithes}
Ornithurae = {Alvarezsauridae + Neornithes} [pretty far off-base]
Ornithothoraces = {Enantiornithes + Neornithes}
Carinatae = {Ichthyornithiformes + Neornithes}
Aves = Neornithes

Any (off-list) clarification of what these definitions should be and any
other important nodes and stems I should know about would be greatly
