Meanwhile we do encourage Innovation by emphasizing X3D extensibility mechanisms: Inline, Script, Prototype, software libraries supporting source-code implementations that generate X3D, etc. etc. New candidate nodes (such as Image Atlas) that rise to the level of broad usefulness can be formally considered as contributions to Web3D Recommended Practice.<o:p></o:p></li></ul><p class=MsoListParagraph><o:p> </o:p></p><ul style='margin-top:0in' type=disc><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo1'><b>Future, 2025+</b>.
