- Improved support for &xml; in search and retrieval. Eventually,
- the goal is for &zebra; to pull double duty as a flexible
- information retrieval engine and high-performance &xml;
- repository. The recent addition of XPath searching is one
- example of the kind of enhancement we're working on.

- There is also the experimental <literal>ALVIS &xslt;</literal>
