#### 16.8.2 Defining a pop-up hotspot

To define a hotspot, in DITA XML apply a dedicated @outputclass to either of the following:

- the text of a cross reference
- text that contains a hypertext link.

If you want content (or an autonumber, or a page reference) from the pop-up material to appear as a hotspot, use a cross reference; if not, use a hypertext link.
