No - the intent with a SOAP (like a <LINK>) is purely advisory.
Whether or not the advice is heeded is up to a combination of the
browser and the user.
i.e. You will always be able to use Arena and browse the unfiltered web.
(Hey! new slogan: "ARENA: The Unfiltered Web Frontier") If you choose to
use the K12-WebBrowser (or let your kids use it), then that is up to you.
It's like bookstores - it's not seen as censorship, but many people choose
not to patronize adult bookstores and also prevent their kids from walking
around the red-light district.
Note that you might also choose not to censor the page but just log the
fact that it occurred. (Cue: "What are those URLs under the bed?"
discussion).
ObWWW: for Meta information - if we want meta information to implement
SOAPs, then the architecture must allow meta information to be
distributed -i.e. I may have SOAPs about your documents, and browsers
which are aware of the fact need to integrate the two sources before
presenting the result.
