When we need to write out the contents in a BodyTagSupport Tag, we can use
BodyContent.writeOut(BodyContent.getEnclosingWriter()) to write everyting 
in the doAfterBody() iteration loop out? Simple as that?

Is it the same as retrieving Strng content from each iteration through 
BodyContent.getString(), then appening Strings from each iteration 
together, then BodyContent.getEnclosingWriter(thisString)? Are they same?

Thanks.
