Thanks for your notes John. I've reset our calendar appointment on Mondays for weekly recurrence.<br>
<br>
Note that Anita intends to consolidate Web3D zoom rooms starting next week. Once that is in place we can switch our rendezvous coordinates and add this regular review event to the Web3D calendar.<br>
<br>
2. Of note regarding LayerSet is that it has a special inheritance hierarchy, which leads to the special handling below. We likely need to consider and apply your fix for each of the conversion stylesheets.<br>
<br>
3. Meanwhile, it turns out that there are 9 active issues on LayerSet in Mantis! I just connected them as related so that they can be addressed coherently, there is definitely some overlap in there.<br>
<br>
* Mantis: View Issues, then apply search filter "LayerSet"<br>

<br>
4. Wondering if you consider "autoclass" a temporary prefix while designing the library. It will certainly simplify authoring if a programmer can simply say<br>
<br>
.addLayerSet((new LayerSet()).setDEF("scene.addChildLayerSetTest"))<br>
<br>
5. Corresponding X3DJSAIL Java invocation looks like this:<br>
<br>
* Filename: HelloWorldProgram.java<br>
* Description: Example "smoke test" program to create an X3D model using the X3D Java Scene Access Interface Library (X3DJSAIL).<br>
* Identifier: <a href="https://www.web3d.org/specifications/java/examples/HelloWorldProgram.java" rel="noreferrer" target="_blank">https://www.web3d.org/specifications/java/examples/HelloWorldProgram.java</a><br>
<br>
scene.addLayerSet (new LayerSetObject("scene.addChildLayerSetTest")); // string is DEF name<br>
<br>
It would be a powerful improvement if the Java might become similarly simplified. Non-trivial, will keep looking at it.<br>
<br>
scene.addLayerSet (new LayerSet ("scene.addChildLayerSetTest")); // string is DEF name<br>
