The TEI abstract model

«
^
»
The TEI abstract model sees a markup scheme (a
schema
) as consisting of a number of discrete
modules
, which can be combined more or less as required.
A schema is made by combining references to modules and optional element over-rides.
Each
element
declares the module it belongs to: elements cannot appear in more than one module.
Each module extends the range of elements and attributes available by adding new members to existing
classes of elements
, or by defining new classes.
