This extension creates sitemaps in .html, .txt, and .xml (google sitemap) formats.
The XML format is explained here: http://www.sitemaps.org/protocol.php
Note that we're using the sitemaplist format for the main file. Every taxon has generates a list of its own products, so the main list is the list of all taxon sitemaps.
The HTML format is effectively the taxon tree, where each node shows the products associated with it.
In HTML and XML modes, a product is only listed (by default) for its first taxon, but you can get it to appear in all of its taxons by setting @allow_duplicates to true.
Yahoo text formats explained here: http://help.yahoo.com/l/us/yahoo/search/siteexplorer/manage/siteexplorer-45.html (do we need to change the filename?)
You can also include a "Sitemap: /sitemap.xml" line in your robots.txt file; some crawlers accept this hint.
There's several ways to inform site engines of (revisions to) your sitemap.
See http://sitemaps.org/protocol.php#informing for info on how to do this via robots.txt and other methods.
Also useful is periodic resubmission via cron/wget/curl etc to a particular url on a search engine, eg see http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=34609
