1) How about dateTime:
yyyy-mm-ddThh:mm:ss
2) Unfortunately, there is no "date" datatype in Xpath. It knows only four:
1)boolean
2)number
3)
string 4)node-set
so your xpath query will be no different from this for strings.
3. Something like (assuming your data are hidden in "dates" tag):
<xsl:copy-of select=".//dates[. > '2002-01-02 10:00' and . < '2002-01-26 23:59']"/>
