    The default location of the Properties window is below the XSLT Map Editor.

  2. Click the center area of the function icon in the canvas pane. The function parameters appear in the right pane of the Properties window.

  3. Edit the function parameters, as desired. Optionally click the Help icon for more information about editing the parameters.

  4. Click the Add icon, represented by the green plus sign (+), to optionally add a new parameter.

  5. To update the XSLT with the changes, click the Apply Changes icon in the upper left corner of the Properties window. Alternatively, click anywhere in the XSLT Map Editor.
