Evidence
Sloan & Walker (2008) recognize is that accessibility concerns tend to focus on the output of learning material authoring, rather than the quality of the authoring process. Some issues to do with the design software itself may limit the ability of authors to produce accessible content. Accessible authoring as a concept is important. These authors emphasize the need for proactive rather than reactive measures.

Sloan & Walker (2008) explain the standard tripartite approach to creating a truly accessible web. This involves adherence to the WCAG-conformant content, created using ATAG-conformant authoring tools, accessed using WAAG-conformant browsing technology. However, they then argue that there are problems with this approach, one is that there is a scarcity of authoring tools that meet the ATAG guidelines. The importance of appropriate authoring tools is mainly due to the fact that increasingly authors are not dedicated web professionals. This places responsibility on web content authoring tools to ensure that all authors can easily create content that is as accessible as possible.
