It is considered in the html5 environment. I was thinking about Custom
Elements as in Web Components. You are right hyphens would be required
everywhere.

It would not be foreign content in the spec. sense but <x3dscript> would be
left alone by the web browser and would be able to have child elements,
correct.

Ok. Thanks.
