+ * the reader is positioned at a sub-node, we cannot capture all the in-scope
+ * namespace bindings. Therefore we cannot re-create a proper SAX event stream

+ * xmlns:b="bar"&gt;&lt;b:sub&gt;a:foo&lt;/b:sub&gt;&lt;/a:root&gt; <p/> And if
+ * you are handed a parser at &lt;b:sub&gt;, then your SAX events should look

+ * not: <p/> &lt;b:sub&gt;a:foo&lt;/b:sub&gt; <p/> <p/> Proposal: we change the
+ * receiver of SAX events (SDOXMLResourceImpl) so that it uses NamespaceContext

+ * parser which knows how to deal with it The common types of name value pairs
+ * we'll come across are
+ * <ul>
+ * <li> String name/QName name - String value
+ * <li> String name/QName name - String[] value
+ * <li> QName name/String name - XMLStreamReader value
+ * <li> QName name/String name - XMLStreamable value
+ * <li> QName name/String name - Java bean
+ * <li> QName name/String name - Datahandler
+ *
+ * </ul>
+ * <p/> As for the attributes, these are the possible combinations in the array
+ * <ul>
+ * <li> String name/QName name - String value
+ * </ul>
+ * Note that certain array methods have been deliberately removed to avoid
+ * complications. The generated code will take the trouble to lay the elements
+ * of the array in the correct order <p/> <p/> Hence there will be a parser impl
+ * that knows how to handle these types, and this parent parser will always
+ * delegate these tasks to the child pullparasers in effect this is one huge
+ * state machine that has only a few states and delegates things down to the
+ * child parsers whenever possible <p/>
