+ * The MemBufFormatTarget is a derivative from XMLFormatTarget, which user code
+ * may plug into DOMLSSerializer to retrieve the serialized XML stream (from DOM Tree)
+ * in a memory buffer.
+ *
+ * The MemBufFormatTarget is initialized to have a memory buffer of 1023 upon
+ * construction, which grows as needed. The buffer will be deleted when
+ * MemBufFormatTarget is destructed; or will be reset when the reset() function
+ * is called.
+ *
+ * The MemBufFormatTarget returns a NULL terminated XMLByte stream upon request,
+ * through the method getRawBuffer(), and user should make its own copy of the
+ * returned buffer if it intends to keep it independent on the state of the
+ * MemBufFormatTarget.
