<p class="MsoNormal">Today while working on XMP metadata transcription from RDF/XML (or TTL) form into X3D/XML form, Jakub and I found that we needed to utilize xml:lang attribute for lossless two-way conversion.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I can think of the following X3D elements that might need to indicate which identification of human language might be appropriate:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Text node (corresponding to ‘string’ field)<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">MetadataString<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><field> and <fieldValue> declarations, if type is SFString/MFString<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Conceivably we might also permit this whenever a description field is present also (Viewpoint, sensors, etc.).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Not looking to change X3D expressive power but think that xml:lang information ought to be permissible in X3D XML encoding since it is an allowed part of XML.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thus am planning to add xml:lang as indicated above in the X3D XML Schema and X3D XML DOCTYPE to avoid incorrect, misleading validation errors.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any other considerations appropriate? Will enter Mantis issue when ready to proceed. All comments welcome.<o:p></o:p></p>
