Some elements contain character data instead of subelements. These elements have definitions of the following format:
<!ELEMENT element-name (#PCDATA)/>
For example:
<!ELEMENT description (#PCDATA)/>
In the sun-web.xml file, white space is treated as part of the data in a data element. Therefore, no extra white space should appear before or after the data delimited by a data element. For example:
<description/>class name of session manager</description>
