Why XSLT can't transform CDATA which contains a blank String

[littlecpu]

for example

DocumentBuilderFactory dbf= DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocumentBuilder().newDocument();
doc.appendChild(doc.createElement("ROOT"));
doc.getDocumentElement().appendChild(doc.createCDATASection(""));

when I use javax.xml.transform.Transformer to transform this Document,
the xslt result is:

<?xml version="1.0" encoding="UTF-8"?>
<ROOT/>

but I want to get

<?xml version="1.0" encoding="UTF-8"?>
<ROOT><![CDATA[]]></ROOT>

Anyone can help???

Thanks!

doc.createCDATASection("")有问题呀，
doc.createCDATASection(" ")，你再试试！
