using "and" / "or"

Is there an "and" or a "or" idea available in XSL, in Javascript we can use
&& and the !.
I want to do this check below and to see if num_at_station ="1" and/or
num_at_station ="2" but I don't want to use the same code twice making it
redundant..... so if it's 1 or 2 show one thing otherwise show the
rest......
Is this "and" "or" idea avaible to suit my needs

          <xsl:choose>
          <xsl:when test="num_at_station='1'">
                 <tr>
                   <td width="83">station is 1 or 2  </td>    		
                 </tr>
	  </xsl:when>
	  <xsl:otherwise>
                 <tr>
                   <td width="83">everything else</td>
                 </tr>
          </xsl:otherwise>
        </xsl:choose>


Please let me know ASAP.
Thanks.
