package com.sun.org.apache.xerces.internal.dom;

Text nodes hold the non-markup, non-Entity content of
an Element or Attribute.
 When a document is first made available to the DOM, there is only one Text object for each block of adjacent plain-text. Users (ie, applications) may create multiple adjacent Texts during editing -- see Node.normalize for discussion. 

Note that CDATASection is a subclass of Text. This is conceptually
valid, since they're really just two different ways of quoting
characters when they're written out as part of an XML stream.
