| <p>The term “at-risk” is a W3C Process term-of-art, and does not | ||
| necessarily imply that the feature is in danger of being dropped or | ||
| delayed. It means that the Working Group believes the feature may have | ||
| difficulty being interoperably implemented in a timely manner, and | ||
| marking it as such allows the Working Group to drop the feature if | ||
| necessary when transitioning to the Proposed Recommendation stage | ||
| without having to publish a new Candidate Recommendation omitting the | ||
| feature.</p> | ||
