Amazonのエディトリアルレビューより

Product Description

XHTML(tm) 1.0: The Extensible HyperText Markup Language defines XHTML 1.0, a reformulation of HTML 4 as an XML 1.0 application. XHTML 1.0 is the first document type in the XHTML family. It is a reformulation of the three HTML 4 document types as applications of XML 1.0 [XML]. It is intended to be used as a language for content that is both XML-conforming and, if some simple guidelines are followed, operates in HTML 4 conforming user agents. Developers who migrate their content to XHTML 1.0 will realize the following benefits:

* XHTML documents are XML conforming. As such, they are readily viewed, edited, and validated with standard XML tools.

* XHTML documents can be written to operate as well or better than they did before in existing HTML 4-conforming user agents as well as in new, XHTML 1.0 conforming user agents.

* XHTML documents can utilize applications (e.g. scripts and applets) that rely upon either the HTML Document Object Model or the XML Document Object Model [DOM].

* As the XHTML family evolves, documents conforming to XHTML 1.0 will be more likely to interoperate within and among various XHTML environments.

This book is a printed version of the XHTML specification available from the W3C.
