You need to add containerField="value" to the "<MetadataXxx ...>"
children inside "<MetadataSet ...>".
Reason: the default containerField of MetadataXxx nodes is "metadata".
This makes indeed cumbersome behavior in case of children of
"<MetadataSet ...>", that you usually want placed in MetadataSet.value
(MFNode), not in MetadataSet.metadata (SFNode). But there's no easy
solution otherwise -- we need default containerField of MetadataXxx
nodes to be "metadata" to work naturally outside of MetadataSet. And
since X3D XML encoding is general, it cannot have special rules like
"containerField default is X in this context, Y in that context" --
that would complicate X3D browsers implementations just for this
specific case.
Note that the attached X3D model actually has it correct in 1x
MetadataString. But then 4x other MetadataString, and 1x
MetadataFloat, have it wrong.
,
Here's the relevant piece, with some whitespace added by me:
"""
<MetadataSet containerField="metadata" name="HAnimHumanoid.info"
reference="https://www.web3d.org/documents/specifications/19774/V2.0/Architecture/ObjectInterfaces.html#Humanoid">
<MetadataString name="authorName" value=""Jin Hoon Lee and
Min Joo Lee, Chul Hee Jung and Myeong Won Lee""
containerField="value"></MetadataString>
<MetadataString name="authorEmail"
value=""myeongwonlee at gmail.com""></MetadataString>
<MetadataString name="creationDate" value=""31 March
2011""></MetadataString>
<MetadataString name="gender" value=""female""></MetadataString>
<MetadataFloat name="height" value="1.5"></MetadataFloat>
<MetadataString name="humanoidVersion"
value=""2.0""></MetadataString>
</MetadataSet>
"""
Here's the corrected version (makes CGE and view3dscene open without
any warnings):
"""
<MetadataSet containerField="metadata" name="HAnimHumanoid.info"
reference="https://www.web3d.org/documents/specifications/19774/V2.0/Architecture/ObjectInterfaces.html#Humanoid">
<MetadataString name="authorName" value=""Jin Hoon Lee and
Min Joo Lee, Chul Hee Jung and Myeong Won Lee""
containerField="value"></MetadataString>
<MetadataString name="authorEmail"
value=""myeongwonlee at gmail.com""
containerField="value"></MetadataString>
<MetadataString name="creationDate" value=""31 March
2011"" containerField="value"></MetadataString>
<MetadataString name="gender" value=""female""
containerField="value"></MetadataString>
<MetadataFloat name="height" value="1.5"
containerField="value"></MetadataFloat>
<MetadataString name="humanoidVersion" value=""2.0""
containerField="value"></MetadataString>
</MetadataSet>
"""

The viewpoint isn't right, suggestions welcome. Joe, I haven't been able to delete the translations without major problems, I will call you tomorrow.
