Tree controls and text areas can now be multi-select controls.

The behavior of the tree control is integrated with the parameter definition. If a parameter is defined as a single value and that parameter is bound to a tree control, the tree control uses radio buttons for each node in the hierarchy. If the parameter is defined as Multiselect OR or Multiselect AND, and that parameter is bound to a tree control, then the tree control uses check boxes for each node in the hierarchy, enabling you to select multiple nodes.

When the Multiple property is set for a text area control, you can enter data values separated by semicolons, commas, or carriage returns.
