The Web Editing Working Group has published a First Public Working Draft of ContentEditable, a collection of proposals developed by the group. Some of these proposals are further defined in EditContext API, which supersedes this document. The Working Group ceased work on this specification in 2022 prior to publishing a First Public Working Draft (FPWD). This FPWD is intended to archive the prior work. Following the publication of this FPWD the Working Group intends to publish this document as a Discontinued Draft and cease further work on it. This does not affect the definition of contenteditable=true, contenteditable=false and contenteditable=plaintext-only as they can be found in [HTML]. Nor does it affect execCommand which is described in another unofficial draft document.
