Re: [xml-dev] What is the use of non-leafElement' VALUE ?

[Jim Melton <jim.melton@acm.org>]

Saha,

Easy: Consider the following markup:

<book>
  <title>Some Useful Stuff</title>
    <chapter>
      <para>This demonstrates the value of
<emph>mixed</emph> content.</para>
    </chapter>
</book>

There is real meaning associated with having "value" in the
<para> element other than the "value" contains in the
sub-element <emph>. 

'Nuff said,
   Jim
