[boost] How to make boost write_xml not escape angle brackets?

Hi all, I am trying to write some data in a xml file using boost write_xml() function. My data has some angle brackets in it e.g. <![CDATA[name]]> . But when I use boost::property_tree::write_xml() to write the data node to xml file it escapes the angle brackets to < and > tags. I even tried using unicode \x3C , \x3E but still it escapes them. Is there any way to tell boost to not escape the characters in a non html safe way ? Regards, Ananyo Maiti
