# Module XHTML

    module XHTML: sig .. end

Typesafe constructors for XHTML 1.1 documents.
See also W3C Recommendation

    module type T = sig .. end

    module type T_01_01 = T

An alias for XHTML 1.1 (for symmetry):

    module type T_01_00 = sig .. end

XHTML 1.0 includes some deprecated features that since have been removed from XHTML 1.1:

    module M: T

    module M_01_01: T_01_01

    module M_01_00: T_01_00
