Thanks John.  Reactions:

- jsail concrete package extends sai interfaces so there should be no gaps in code.
- many getters and setters provided already, please look in javadoc and example programs for what you need.
- X3dToJava.xslt is applied to all 3900 example scenes, which try (and usually succeed) to validate to during build process.
- if there remains an obvious gap, please provide short sample code and we can determine if something else should be needed.

Please do not use SAI abstract methods directly when implementing Java models using X3DJSAIL, that can be confusing and is intended for (a) compliance with SAI and (b) internal usage.

> Discuss whether X3DJSONLD’s code generation needs to be improved and also further warnings on test files (HAnim v2 Korean Motion examples), once Java compiled cleanly (Don’s Java at this point).

Everything I've been doing/reporting has remained compatible across all our tools languages and encodings.  If I hit a problem will report it.
