Sorry you had a hangup... it should be OK, I've tested it extensively and kept updates going through the weekend. Please refresh.

One nonuniformity is that i am locally building X3D object model and classes from the following directory as scratch,

	C:\x3d-code\www.web3d.org\x3d\stylesheets\java

then pushing/publishing to a different subtree at

	http://www.web3d.org/specifications/java

Hopefully these details are helpful:

	http://www.web3d.org/specifications/java/X3dJavaSceneAuthoringInterface.html#Codebase

Further trouble reports welcome

> As with other Java constructs, these field names get automatically generated into the Java SAI Library by using information found the X3D Object Model.  So these string constants are always correct and always available to the programmer.  It is always valuable to try pushing error detection from end-user run time (ouch) to programmer compile time (aha, a bug to fix).  These good programming practices add up, and all help X3D Quality Assurance (QA).
