Description

Function max() returns the maximum value of the result of converting the string-values of each node in the argument node-set to a number. "Maximum" is determined with the > operator. If the parameter is an empty node-set, or if any of the nodes evaluate to NaN, the return value is NaN.

      <ex:root>
         <ex:value>2</ex:value>
         <ex:value>6</ex:value>
      </ex:root>
   </xforms:instance>
</xforms:model>
 ...
<xforms:group>
   <xforms:output value="max(ex:value)">
      <xforms:label>Maximum : </xforms:label>
   </xforms:output>
</xforms:group>
