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, there should be no extra white space before or after the data delimited by a data element. For example:
<description>class name of session manager</description>
