Hm, I've had a look at the specs but I don't see how I could use marked
content to do the same thing as optional content.
What I would need is something like a switch that makes older viewers
ignore all content. In the meantime, I've come across the BX ... EX
compatibility operators. However, they will only ignore unknown
operators, not the content.
