2 This is the HTML 4.01 Transitional DTD, which includes
3 presentation attributes and elements that W3C expects to phase out
4 as support for style sheets matures. Authors should use the Strict
5 DTD when possible, but may use the Transitional DTD when support
6 for presentation attribute and elements is required.
7
8 HTML 4 includes mechanisms for style sheets, scripting,
9 embedding objects, improved support for right to left and mixed
10 direction text, and enhancements to forms for improved
11 accessibility for people with disabilities.

25 The HTML 4.01 specification includes additional
26 syntactic constraints that cannot be expressed within
27 the DTDs.

47 The FPI for the Strict HTML 4.01 DTD is:

55 Authors should use the Strict DTD unless they need the
56 presentation control for user agents that don't (adequately)
57 support style sheets.
