XMLStreamWriter - ability to stream a CDATA section?

[Jaikiran Pai]

I'm looking for some information regarding the APIs on 
javax.xml.stream.XMLStreamWriter which allows streaming of XML content 
to a target output. Most of the APIs on it allow for streaming the 
content out. However, there's the writeCData[1] API which takes a String 
object as a param and writes out the content as one whole CDATA section. 
I don't see a way where I can avoid loading the entire content, which in 
some cases can be large, in memory.

Is there a reason why such a construct hasn't been made available for 
writing out CDATA? Something like:

      writeStartCData() - starts a CDATA section
      for(....) {
          // incrementally write out the CDATA content
          writeCData(char[], off, len) // or something similar
      }
      writeEndCData() - ends a CDATA section that was previous started

Would it make sense to add such an API to that class?
