This appendix is normative.
These DTDs and entity sets form a normative part of this specification. The complete set of DTD files together with an XML declaration and SGML Open Catalog is included in the zip file and the gzip'd tar file for this specification. Users looking for local copies of the DTDs to work with should download and use those archives rather than using the specific DTDs referenced below.
These DTDs approximate the HTML 4 DTDs. The W3C recommends that you use the authoritative versions of these DTDs at their defined SYSTEM identifiers when validating content. If you need to use these DTDs locally you should download one of the archives of this version. For completeness, the normative versions of the DTDs are included here:
The file DTD/xhtml1-strict.dtd is a normative part of this specification. Its annotated contents are included here for completeness.
