[x3d-public] Hyperlink and form support

[Leonard Daly]

Hi Albert,

X3D (in strict specification sense) cannot be integrated with HTML5. 
There are fundamental incompatibilities that prevent that from happening 
(see node and attribution case, Script node name, name scoping, and 
event handling for major examples). I started developing XSeen 
(https://XSeen.org/) to address to issues. XSeen is fully integrated 
with HTML5 allowing mixed DOM and 3D content throughout the page.

The W3C Immersive Web WG is addressing many of the issues you have 
raised in this and other emails. Some of these issues end up being much 
more involved than what appears on the surface, especially when 
involving device fingerprinting, security considerations, or user 
permissions.

In particular your question about incorporating 2D web pages into 3D 
scene very quickly starts down the part of security considerations. For 
example, does the 2D content have access to the 3D space? Does the 3D 
context have access to the 2D pages? How do you ensure that a click on a 
2D page element (e.g., checkbox) really gets handled by the 2D page and 
is not completely intercepted by something in the 3D space?

If you are developing some hardware with associated software that will 
work in the XR space, it might be very good to get involved with them. I 
can provide contact information if you need it.
