the use of String.intern() for literals

I have found the following line in org.apache.xerces.impl.Constants:
    public static final String NS_DTD ="http://www.w3.org/TR/REC-xml".intern();

@version $Id: Constants.java,v 1.31 2003/07/18 17:34:37 elena Exp $

Why the author used intern() for string literal?
