<P>
An encapsulation of the evaluation of the body of an action so it is
 available to a tag handler.  BodyContent is a subclass of JspWriter.

 <p>
 Note that the content of BodyContent is the result of evaluation, so
 it will not contain actions and the like, but the result of their
 invocation.
 
 <p>
 BodyContent has methods to convert its contents into
 a String, to read its contents, and to clear the contents.

 <p>
 The buffer size of a BodyContent object is unbounded.  A
 BodyContent object cannot be in autoFlush mode.  It is not possible to
 invoke flush on a BodyContent object, as there is no backing stream.

 <p>
 Instances of BodyContent are created by invoking the pushBody and
 popBody methods of the PageContext class.  A BodyContent is enclosed
 within another JspWriter (maybe another BodyContent object) following
 the structure of their associated actions.

 <p>
 A BodyContent is made available to a BodyTag through a setBodyContent()
 call.  The tag handler can use the object until after the call to
 doEndTag().
