OK.  Thanks.

I updated manually and tested the latest DTD(s) in the NPS branch.

The current update fixed the Xj3D binary compression errors that
were getting thrown by various field defaults of 1.5708 > Math.PI / 2

I regenerated all of the .x3db examples for two archives,
X3dForWebAuthors and ConformanceNist.  This provides a pretty
thorough selection of X3D nodes (247 + 732 models total).
No validation problems noted. This tests Xj3D validation
using the DTD each time.

(Xj3D binary compression does have trouble with prototypes and some
of the newer nodes, but those are other topics for another time.)

Wondering what other checks beside scene validation would need to be
performed prior to updating the trunk with latest DTDs?
