+		# output::
+		#   Where to write the string.  Defaults to $stdout
+		# indent::
+		#   An integer.  If -1, no indenting will be used; otherwise, the
+		#   indentation will be this number of spaces, and children will be
+		#   indented an additional amount.  Defaults to -1.
+		# transitive::
+		#   If transitive is true and indent is >= 0, then the output will be
+		#   pretty-printed in such a way that the added whitespace does not affect
+		#   the absolute *value* of the document -- that is, it leaves the value
+		#   and number of Text nodes in the document unchanged.
+		# ie_hack::
+		#   Internet Explorer is the worst piece of crap to have ever been
+		#   written, with the possible exception of Windows itself.  Since IE is
+		#   unable to parse proper XML, we have to provide a hack to generate XML
+		#   that IE's limited abilities can handle.  This hack inserts a space 
+		#   before the /> on empty tags.
+		#
+		# _Examples_
+		#  c = CData.new( " Some text " )
+		#  c.write( $stdout )     #->  <![CDATA[ Some text ]]>
