This is potentially risky because JavaScript can modify or even create 
the HTML as the file is loading to produce different results. Some HTML 
frameworks (e.g., React.js) load partial content until the region to be 
display is nearly visible to the user, then the entire region is loaded. 
The scene may also contain some vendor-specific scene elements that 
should not be filtered out.

It is probably much easier (and safer) if you only accept straight X3D 
than start mandating that the embedded X3D in HTML follow some very 
specific design constraints.
