XHTML Modularization
XHTML modules provide means for subsetting and extending XHTML. XHTML modules are used for creating new flavors of XHTML, such as XHTML Basic for mobile devices.
Core modules are
* Structure (html, head, body, title...) * Text (h1, h2, h3... p, pre...) * Hypertext (a) * List (ul, li...)
Other modules include applet, image, forms and basic forms.
