How much the tools help or hinder Web authors' attempts at creating accessible design can vary greatly from tool to tool. The Web standards group, W3C , have some recommendations. The biggie is that the authoring tool checks for or asks the author to include equivalent alternative information such as text equivalents, captions, and auditory descriptions at appropriate times. The tool should insist that the author create this alternate content rather than defaulting to the insertion of useless information such as an image filename and size. The tool should provide up front opportunities to add summary information to tables, long descriptions of sound or video content, titles to links, tab order preferences and other accessiblity requirements.
Many tools allow documents created in one format to be saved as HTML documents.
If content is rearranged due to layout considerations, the rearrangement must maintain a sensible reading order. Text shouldn't be converted to images. Styles should be used instead to keep the text as text. Linked items such as footnotes or references should be maintained as hypertext links with return links embedded. For example, list tags should not be used to create indents.
