For other data types you need to wait till XPath 2.0, or use a workaround. For dates in iso format, you can strip the punctuation using translate(), so that 2002-07-23 becomes 20020723, then you can compare dates as numbers. For comparing strings alphabetically, the best solution is probably an extension function, though you can probably do it in XSLT (exploiting xsl:sort) if you're determined enough.
