I used the desert3 link in included message reply, and got the following
error in console. Note that I see DEF in X3DUOM, but it's hidden somewhere
in the standard I think. So there may be some confusion? Why would you
have 2 identical viewpoints?
x_ite.min.js:9 r {_value: h} "DEF" Error: Unkown field 'DEF' in node class
Viewpoint.

Here is the code I used. MFNode is a constructor in ECMAScript SAI
standards, but it may take parameters. I don't know what the right thing
to do is, but I'm willing to learn.
