Not really. It mainly can be used to supply a default, non-empty, value. So, if you say: <xsl:param name="foo" select="'NULL'"/> and then later say <xsl:if test="$foo = 'NULL'> # No value was supplied </xsl:if> that'd do the trick in determining if simply an empty string was supplied. > > http://nachbaur.com/pgpkey.asc > > Uhm, you didn't get the new key right, but I'll take that in a private > e-mail. :-) Blast it! *sigh* :-) - -- Michael A.
