This presence in management messages, or frames, is an oft-overlooked detail of the IEEE 802.11 specification that is critical to debunking the myth of SSID hiding. Management messages are always sent in the clear, even when link encryption (WEP or WPA) is used, so the SSID is visible to anyone who can intercept these frames.
