Css Imports.Changes

Draft 3

• Add @content to the list of disallowed at-rules.

• Allow @media rules within style rules and at-rules. Recent CSS specs allow this, so we shouldn't forbid it.

• Disallow silent comments.

Draft 2

• Explicitly defined the term "canonical URL" as it relates to stylesheets.

• Added a specification for loading plain CSS as an entrypoint file.

• Added a non-normative note explaining that the new import algorithm maintains the semantics of the existing import algorithm, other than supporting plain CSS files.

Draft 1

• Initial draft.
