/**
 * Receives XML serialization event and writes to {@link XmlOutput}.
 * 
 * 

* This object coordinates the overall marshalling efforts across different * content-tree objects and different target formats. * *

* The following CFG gives the proper sequence of method invocation. * *

 * MARSHALLING  :=  ELEMENT
 * ELEMENT      :=  "startElement" NSDECL* "endNamespaceDecls"
 *                        ATTRIBUTE* "endAttributes" BODY "endElement"
 * 
 * NSDECL       :=  "declareNamespace"
 * 
 * ATTRIBUTE    :=  "attribute"
 * ATTVALUES    :=  "text"*
 * 
 * 
 * BODY         :=  ( "text" | ELEMENT )*
 * 
* *

* A marshalling of one element consists of two stages. The first stage is * for marshalling attributes and collecting namespace declarations. * The second stage is for marshalling characters/child elements of that element. * *

* Observe that multiple invocation of "text" is allowed. * *

* Also observe that the namespace declarations are allowed only between * "startElement" and "endAttributes". * *
