However, there are a lot of SGML tools(160 packages at the last count, and 83 major software companies—notincluding the more than 30 independent developers responsible for some veryexcellent public domain and shareware packages). In principle, any SGMLsoftware package should eventually be able to deal with XML documents (whichwas one of the XML design goals, after all). However, rather than list all thepackages, I have listed details of only those packages that already support XMLor have announced that a version of their software that supports XML willbe available in the near future.</P><P>This means, for example, that I have explicitly excluded packages suchas Microsoft's Internet Explorer because version 4.0 currently supports onlyCDF (covered in Chapter 18, "Potential Applications of XML"), and it isanyone's guess when version 5.0 (which should fully support XML) will be released.</P><P>Be warned that as XML becomes more and more accepted, you canexpect existing SGML packages to be very quickly converted to handle XML, sothe list of available software packages can change very quickly.</P><H4><A NAME="ch16_ 14">ADEPT*Editor</A></H4><P>ADEPT*Editor (ArborText, Inc., 1000 Visitors Way, Suite 100, AnnArbor, MI 48108-2700, USA, info@arbortext.com) was originally an excellentnative SGML editor.

A beta testversion of this tool that supports the XML language (but not XML linking),called Symposia doc+, was released in July 1997.

That isa surprisingly large number, considering that the XML standard has notyet reached its final form. Some of the packages might sound a little "roughand ready," but don't let appearances fool you. Obviously, you can expect thatthe package released by Microsoft reaches a certain standard (although whatexactly that standard is might be a topic for some discussion), but some ofthe packages (such as NXP) are so central to XML that they were used duringthe formulation of the XML standard to try to determine whether certainactions were feasible. Such an approach says a lot about the software, <BR>but it also emphasizes the very practical spirit that underpins all the XML <BR>activities.<P><CENTER><A HREF="0301-0304.html">Previous</A> | <A HREF="../ewtoc.html">Table of Contents</A> | <A HREF="../ch17/0309-0312.html">Next</A></CENTER></P></TD></TR></TABLE></BODY></HTML>⌨️ 快捷键说明
