XMLDoc for Delphi unit name

Question

Is it possible to document unit purpose in Delphi using <summary> XMLDoc tag? How?

I've tried put summary both before unit:

/// <summary> Unit purpose: test </summary>
unit Test;

and after:

unit Test;
/// <summary> Unit purpose: test </summary>

Both approaches gives nothing. Checked by hovering over the unit name in the other unit. At the same time hovering works for other identifiers in the same units

According to Embarcadero's documentation:

XML Documentation Comments

You can use the following elements in XML DOC comments:

<summary>

A summary of the target function or class

So no, it does not appear that you can apply a <summary> to the unit as a whole.
