XHTML Basic


Became a Recommendation on 19 December 2000

A subset of XHTML 1.0 Strict as well as XHTML 1.1, built from XHTML modules

Designed for Web clients that do not support the full set of XHTML features; a common base that may be extended

A number of commercial implementations as well as open source implementations (e.g. Amaya, X-Smiles) exist
