The objective was to keep track of point index in order of appearance according to names assigned to standard surface features. At the first transcoding from classic to xml those comments were transported into a big comment at the end of the xml. Then when back to classic, of course those comments remained basically disassociated from the individual point that was intended to be documented. <o:p></o:p></p><p class=MsoNormal>I sort of knew what was going to happen because when the mf points field becomes an attr, it don’t like to find embedded comments. The xml mf field only contains sfs to make mfs and needs comment childs or meta childs, while the classic mf can have a comment for each individual sf in the mf list. So I didn’t compensate using a different style of comments and so the reference became basically useless unless the transform rules are known. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>What has changed since we chose our sf and mf xmlization path? Well for one thing it ought to be a lot easier to just say Hey if we wanna put comments for each sf in the mf list, then OK Thus it will be ok to comment an sf in an mf with end of line comment for the mf numeric lists. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Same with the json/gltF encodings, embedded comment to document an sf in the mf should be ok, and directly transcodable from xml or json or gltf to classic. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks, <o:p></o:p></p><p class=MsoNormal>Joe<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:brutzman@nps.edu">Brutzman, Donald (Don) (CIV)</a><br><b>Sent: </b>Wednesday, February 9, 2022 9:01 PM<br><b>To: </b><a href="mailto:yottzumm@gmail.com">John Carlson</a><br><b>Cc: </b><a href="mailto:x3d-public@web3d.org">X3D Graphics public mailing list</a><br><b>Subject: </b>Re: [x3d-public] X3D JSON Schema - validating comments inside a USEnode</p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>[Adjusted subject line to match topic] Hello again John, thanks for further detail.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The following is valid XML:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> <Shape USE='Torus'><br> <!-- Knot --><br> </Shape><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>As is the following VRML fragment, if found in the right place:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='text-indent:.5in'>USE Torus # Knot<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Certainly the most common place to find comments in practice will be as children within a grouping node, or at the top of a scene.
