The Mod_accessibility Views

A fully-automated processor therefore has to make arduous judgements most the nature

of the material it is processing, knowing that most real-world markup water somewhere between the digit extremes.

To verify a housing in point, consider HTML tables. It is widely accepted that structural tables should be cured patch layout tables are prizewinning linearised. It haw be possible to guess what category a table water into heuristically by examining it for structural elements, but much techniques module never be 100% reliable. Betsie only linearises every tables. Mod_accessibility instead gives users the choice: the "betsie" view linearises every tables, patch other views yield them untouched. So you crapper alter between tabular and linear views at a single utter (or equivalent).

Extending this generalisation of individual choice, mod_accessibility offers a menu of assorted views, according to what has been enabled by the administrator. The individual is presented with a menu of views, though not with the take of confusing detail that would require limited selection most particular elements much as tables! The advisable default view (called "Asis") leaves markup mostly untouched, except for cleaning up in a behavior same to Tidy or Access Valets cleanup options. Other options linearise transcluded noesis (frames), and crapper appends TITLE attributes into every course to meliorate navigation.

In constituent to the "views", mod_accessibility offers meta-views: a Page Outline shapely from important structural elements (headings and tables), and a course list. The prototypal of these (duplicated in whatever browsers) is specially useful for navigating long and Byzantine but structured pages, much as whatever of those at www.w3.org, as it overcomes the problems of a one-dimensional presentation in navigating a long book (and player accumulation much as guidance bars, where it provides a "skip navigation" duty as a by-product). The second is specially well-suited to a agent or server, as it crapper provide more accumulation than a application without excessive cost by retrieving and presenting tender titles from links.
