| <p> This page describes some of the changes which should be expected |
| in Expat 3. These are intended as notes made by the developers as |
| things get thought through; these can change at any time. This is |
| <em>not</em> a projected feature list for Expat 3; to learn about the |
| target features, please read the <cite><a href="roadmap.html">Expat |
| Development Roadmap</a></cite>. The changes described here are much |
| more focused on the details of Expat 3, and no attempt has been made |
| to balance the description of small changes with major new feature |
| development. </p> |
| |
| <p> This list is not complete; we'll add to this as we think of things |
| and have time to write about them. </p> |
| |
| <ul> |
| <li> Support for XML 1.1 and the corresponding namespaces updates. </li> |
| |
| <li> The signature of the <code>XML_ParserReset()</code> method will |
| grow an additional argument allowing specification of what should be |
| reset. See <a href= |
| "http://sourceforge.net/tracker/index.php?func=detail&aid=1109116&group_id=10127&atid=110127" |
| >bug report 1109116: <em>Optimize implementation of |
| XML_ParserReset</em></a> for more information. </li> |
| |
| <li> All structural event callback functions will return an |
| <code>XML_Status</code> value that the parser will check. This will |
| allow an application to stop or suspend processing without having to |
| use <code>setjmp()</code>/<code>longjmp()</code> hackery. </li> |
| |
| <li> The parser will support suspension of parsing to allow an |
| application to pause parsing temporarily. A new |
| <code>XML_Status</code> value, <code>XML_STATUS_SUSPEND</code>, can |
| be returned by the event callbacks to indicate that Expat should |
| suspend parsing; the parser will then return from |
| <code>XML_Parse()</code>, returning <code>XML_STATUS_SUSPEND</code>. |
| Applications can resume parsing by calling |
| <code>XML_ParseResume()</code>. </li> |
| </ul> |
