W3C standards process in 1998
In May 1998, the W3C formalized its standards process with the publication of
the document “World Wide Web Consortium Process.” It listed three stages a
standard had to go through:
Working Draft (WD) — The proposed standard may go through several
drafts. Once the standard has stabilized, the editor issues a Last Call for
comments, and then the standard can move on to the next stage.
Proposed Recommendation (PR) — The Proposed Recommendation stage
lasts at least four weeks. A PR is voted on by W3C members. After the vote,
the standard is either returned to the Working Draft stage or, perhaps with
modifications, advances to be a full recommendation.
W3C Recommendation (R) — A Recommendation indicates that consensus
has been reached among W3C Members and the specification is appropriate
for widespread use. After the standard has become a Recommendation, only
minor revisions are allowed to correct minor errors or clarify issues.

of objects, so you'll frequently hear it referred to as a DOM tree . With
the release of Netscape Navigator (now Communicator) 4.0 and IE
4.0, the DOM became a complete interface, and developers were able
