w3c standards

I am searching for a WYSIWYG editor, which is build using the ATAG standards in mind.
Does any of you know an editor who complies to these standards?

I'd like to share some quick thoughts on how Drupal Data could be described in RDF. The attached schema represents the mappings between the current Drupal data structure and the proposed RDF Schema, reusing existing ontologies such as Dublin Core, FOAF, SIOC and SKOS.

The green circles represent the Drupal objects (node, revision, user, role, term), with their equivalent RDF class. The rectangles are the values used in Drupal. It's important to differentiate a class from its actual instances (resources) which are each defined by a unique URI, see the examples below. This schema is meant to be simple, incomplete, and to show the main core features.
Comment and Node are 2 different elements in Drupal, they can be combined in the same Class with the recursive property sioc:has_reply (Comment as Node). Node and Revision objects are separate here as they are in the Drupal Data structure, but they could fundamentally be merged as well.

I presented SIOC at DrupalCon Barcelona, and showed how it can be used to describe online communities. The SIOC sioc:Item class which I used here as equivalent of a Node is a broad Class with many sub-types: AddressBook, AnnotationSet, AudioChannel, BookmarkFolder, MailingList, MessageBoard, BlogPost, BoardPost, WikiArticle... See the SIOC Types Module for more details.

As most of you may already know from some of my comments on here, I'm not a standards extremist by any means... I think the design should take the lead not the standardized code.

The main thing that I think is just silly about this whole standardized code discussion is that it keeps changing... what is *standard* today is not acceptible tomorrow.

I do however believe that standardized code is important and accessibility is important. But that is not the goal of this designer. My goal is to produce a great looking site, and as long as I can do that using xhtml and make it accessible to the largest audience I will (especially if my client is willing to pay for the extra time involved in building a site that way.) There are huge benifits to building sites using standards, for example SEO and accessiblity, and I'm with you all there 100%.
