You have seen that there are two types of XML entities:</P><UL><LI> Text entities are effectively part of the XML document.<LI> Binary entities are any other type of resource.</UL><P>I briefly discussed the main uses to which entities can be put, and how torefer to both general entities and parameter entities. (The latter are useful onlywhen creating a DTD.)</P><P>After this, I pointed out that XML entities are a slightly abstract conceptthat can be physically implemented in a number of ways. The two mostcommon methods are to hold entities as files and to store them as part of an XMLdocument.</P><P>I then covered how logical and physical structures can nest within eachother in XML, and I finished this discussion by describing the built-in entitiesincluded with XML.</P><P>I then showed how to insert references to any individual character in theISO 10646 character set. The chapter was rounded off with a broader review ofthe character encoding issues and strategies in XML.</P><P>The next chapter looks at what is inside XML DTDs. They are thecontrol center that determines what is allowed in your XML documents.</P><A NAME="PAGENUM-122"><P>Page 122</P></A><P><CENTER><A HREF="0117-0120.html">Previous</A> | <A HREF="../ewtoc.html">Table of Contents</A> | <A HREF="../ch08/0123-0126.html">Next</A></CENTER></P></TD></TR></TABLE></BODY></HTML>
