+ * not: <p/> &lt;b:sub&gt;a:foo&lt;/b:sub&gt; <p/> <p/> Proposal: we change the

+/**
+ * This is the new implementation of the XMLFramentStreamReader. The approach
+ * here is simple When the pull parser needs to generate events for a particular
+ * name-value(s) pair it always hands over (delegates) the task to another pull
+ * 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/>
