Generally, the document maturity process is as follows: It first starts off as a Working Draft (WD), where the W3C publishes the draft for review by the community, W3C Member, the public, and other technical organizations. After WD, it falls in the Recommendation Track. In this process, the first level is Candidate Recommendation (CR). A CR is a document the W3C believes has been widely reviewed and satisfies the Working Group’s technical requirements. W3C Publishes a CR to get information on implementation experience. If it passes the CR level, it becomes a Proposed Recommendation (PR). A PR is a mature technical report that has been widely reviewed for technical soundness and implement-ability. W3C sends the report to the W3C Advisory Committee for final endorsement. Lastly, the specification becomes a W3C Recommendation (REC). This is a specification that has received the endorsement of the W3C members and the director. W3C Recommends the wide deployment of its Recommendations, though it’s safe to implement something of a PR maturity level so as long as your target audience browsers support it’s features.
