<br>
At the bottom of the report, the lines showing improper coding was blank so here is example.<br>
<br>
The sequence:<br>
Transform DEF='BorderFlower01' .../<br>
then<br>
Transform DEF='FlowerSpecial' ...<br>
Shape USE='BorderFlower01' /<br>
/<br>
<br>
Does not match ShapeChildContentModel<br>
Contained node's relationship to its parent node is wrong,<br>
Shape has no children so wrong containerfield for Transform.<br>
Transform needs containerField=children<br>
Shape is not a Grouping Node.<br>
<br>
<br>
Thanks Again,<br>
Joe<br>

Comment on 19776-1: XML Encoding - V3.3<br>
4.3.4<br>
<a href="https://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#DEFAndUSEAttributeSyntax" rel="noreferrer" target="_blank">https://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#DEFAndUSEAttributeSyntax</a><br>
<br>
-----------------<br>
Recent posts to the X3D-Public mailing list have pointed out that there is a<br>
discrepancy among browsers in how they handle the<br>
DEF/USE statements if the XML elements in the XML encoding have disparate<br>
names.<br>
<a href="http://web3d.org/pipermail/x3d-public_web3d.org/2024-January/020212.html" rel="noreferrer" target="_blank">http://web3d.org/pipermail/x3d-public_web3d.org/2024-January/020212.html</a><br>
<br>
I recommend the XML encoding spec be edited, in the next standard submission<br>
cycle, to clarify that it is invalid for XML elements with different names<br>
(i.e. encoding different X3D nodes) to have matching values of DEF/USE<br>
attributes.)<br>
<br>
Proposed wording to be added to what is now Section 4.3.4 of the 19776-1<br>
document at version 3.3:<br>
<a href="https://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#DEFAndUSEAttributeSyntax" rel="noreferrer" target="_blank">https://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#DEFAndUSEAttributeSyntax</a><br>
<br>
Suggest adding this text:<br>
<br>
-----------------------------------------------------------------------------<br>
It is a validation error when an XML element with a DEF attribute matches<br>
another element's USE attribute but has a different XML element name.<br>
<br>
Example of invalid XML encoding:<br>
