1. Michalis, thanks for a great trouble report.
I believe the conversion errors are now fixed in X3dToVrml.xslt stylesheet,
updated model at
*
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Skin/JoeKick.x3
dv
Unfortunately I discovered that a lot of type checking within that
stylesheet isn't really effective due to a puzzling logic error, so there
may well be other errors like this. More work will likely be needed.
Wondering if you have a command-line mode for validating VRML/ClassicVRML
models with view3dscene? Perhaps I might be able to add that to our
regression testing build scripts.
2. Joe, it's your model, so please send any texture coordinate changes you
may have and I will update the .x3d model in the archives.

Meanwhile there are plenty of warnings from Schematron. They seem accurate.
The flagged parent-child relationships are either a problem in the model, or
else (less likely) a problem in the diagnostics (which are autogenerated
from X3DUOM).
I thought that possibly they are related to your use of loa='3' complexity,
but diagnostics looked the same for loa='4'.

Subject: [x3d-public] JoeKick H-Anim example - error in X3D classic encoding
"Joe Kick" example linked from
<https://www.web3d.org/x3d/content/examples/HumanoidAnimation/>
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/ ,

, 2 errors:
1. The "ClassicVRML" encoding version (
<https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Skin/JoeKick.x
3dv>
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Skin/JoeKick.x3
dv
) seems to be incorrectly converted from XML to classic encoding. It
contains
"""
DEF Joe_skull_tip_raiser_action HAnimDisplacer { coordIndex 0 1 2 3 4 5 6 7
8 9 displacements 0 0.15 0 0 ...
name "skull_tip_raiser_action"
}
"""
so the coordIndex and displacements fields miss [ ] around their values.
"coordIndex" is MFInt32, "displacements" is MFVec3f, they both require [ ]
in classic encoding if you want to have a list of arbitrary number of
elements. If no [ ] are used, the classic encoding parsers have to assume
they contain 1 item (1 integer on "coordIndex", 1 vector == 3 floats on
"displacements"). Currently parsing this fails, as parser sees unexpected
numbers in the middle of HAnimDisplacer.
This problem is not present in XML encoding, where no [ ] are used, the
lists are in separate XML attributes.
2. The XML encoding version contains invalid number of texture coordinates,
we have discussed in previously on this list:
X3D: Invalid number of items in an attribute array for shape
"Joe_Humanoid/Joe_Kick/Joe_Shape/IndexedFaceSet(Joe_skin_IndexedFaceSet)":
Invalid index: 9, but we have 4 items in 2D texture coordinates
