Other DTDs</H1 ><P >A brief digression into other DTDs may help make clear what parts of the previous section were specific to DocBook and what parts are general to all structural-markup languages.</P ><P ><A HREF="http://www.tei-c.org/" TARGET="_top" >TEI</A > (Text Encoding Initiative) is a large, elaborate DTD used primarily in academia for computer transcription of literary texts. TEI's Unix-based toolchains use many of the same tools that are involved with DocBook, but with different stylesheets and (of course) a different DTD.</P ><P >XHTML, the latest version of HTML, is also an XML application described by a DTD, which explains the family resemblance between XHTML and DocBook tags. The XHTML toolchain consists of web browsers and a number of ad-hoc HTML-to-print utilities.</P ><P >Many other XML DTDs are maintained to help people exchange structured information in fields as diverse as bioinformatics and banking. You can look at a <A HREF="http://www.xml.com/pub/rg/DTD_Repositories" TARGET="_top" > list of repositories</A > to get some idea of the variety out there.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="x78.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="x109.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Document Type Definitions</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >The DocBook toolchain</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
