We have tried to make link text meaningful out of context. Many browsers designed for blind or visually impaired users permit jumping through a page from link to link so that intervening or surrounding context information is ignored. For the same reason, no two links on a page should have the same link text if they point to different places. Not all browsers support these constructs and most screen readers have difficulty presenting tables in spoken form. The start and end of the table was clearly delimited from the running text and a HTML 3.0 version of the table was also provided via a link off the main document.
Research continues into how to present tables for blind and visually impaired users.
The above is just our work-around, not a complete solution. Although some progress is being made in this area with browser technology, forms can exclude some users. These extensions are sometimes designed to make one browser appear superior to another, but they exclude some users who prefer or may have to use their own choice of browser. We have tried to eliminate spelling errors. A speech synthesiser may produce strange results if given an incorrectly spelled word.
