-/**
- * Adapter that converts from StAX to SAX event streams. Currently the following
- * SAX events are not generated:
- * <ul>
- * <li>ignorableWhitespace</li>
- * <li>skippedEntity</li>
- * <ul>
- * Also the following StAX events are not mapped:
- * <ul>
- * <li>CDATA</li>
- * <li>COMMENT</li>
- * <li>DTD</li>
- * <li>ENTITY_DECLARATION</li>
- * <li>ENTITY_REFERENCE</li>
- * <li>NOTATION_DECLARATION</li>
- * <li>SPACE</li>
- * </ul>
- * StAX ATTRIBUTE events are ignored but the equivalent attributes (derived from
- * the START_ELEMENT event) are supplied in the SAX startElement event's
- * Attributes parameter. If the adaptor is configured to pass namespace prefixes
- * then namespace information will also be included in the Attributes; StAX
- * NAMESPACE events are ignored. <p/> Another issue is namespace processing. If
- * 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
- * from a StAX parser. <p/> For example <p/> &lt;a:root xmlns:a="foo"
- * 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
- * like: <p/> &lt;b:sub xmlns:a="foo" xmlns:b="bar"&gt;a:foo&lt;/b:sub&gt; <p/>
- * 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
- * to resolve prefix (as opposed to record start/endPrefixMappings and use it
- * for resolution.)
