- DTD/Schema: bits needed by a machine to interpret a document encoded in
accordance with the usage of some application or community of
discourse (syntax, semantics, style, etc also called the Manifest)
- XML accessible application : enables and promotes the
creation of accessible documents
- accessible document: can be equally understood (modulo
some graceful transformation) by its
targeted audience regardless of the device used to access it.
- Graceful transformation a property of a system that can still
function relatively error free when the system is damaged or when the
input stimuli is incomplete. In such systems, removing a symbol token
only results in the loss of the information stored in that token,
with no abrupt performance decline of the overall process.
