Comment (including rationale for proposed change):
I recommend this requirement be moved to SC1. If descriptions of an image are SC1, then are not descriptions or titles of a web page of equal importance? This should be merged with requirements of 2.4.5 and that descriptions/titles should be \"unique\" for collections of a web resources as part of the success criteria.
See UIUC Web Accessibility Best Practices:
I recommend this requirement be moved to SC1 and merged with the requirements of 2.4.5.
We have added "descriptive" to SC 2.4.3 and moved it to level A.
The success criterion does not require that titles be unique because the working group is concerned that requiring uniqueness will lead to titles that are not as descriptive and usable. It may be very difficult to create titles that are descriptive, unique, and reasonably short. For example, a Web page that generates titles dynamically based on its content might need to include part of the dynamic content in the title to ensure that it was unique. We are also concerned that authors may make titles unique mechanically, such as by including a unique number in the title that is unrelated to the content. For these reasons, although we encourage unique titles in the techniques for this SC, we are not including uniqueness in the SC itself.
SC 2.4.5 has been moved to Level AA. It addresses descriptive headings and labels, which may need to be understood in context. While headings may not have sufficient descriptive power in isolation, when viewed in the context of a structured document, they do have sufficient descriptive power.
