  32 <para>If non-zero,
  33 then the exsl:node-set() function is available to be used in
  34 the stylesheet.
  35 If zero, then the function is not available.
  36 This param automatically detects the presence of
  37 the function and does not normally need to be set manually.</para>

  39 <para>This param was created to handle a long-standing
  40 bug in the Xalan processor that fails to detect the
  41 function even though it is available.</para>
