What this control does is allow you to pick from several rendering modes, like:
Standard Health Bar
Image Health Bar
Generic Bar
Generic Image Bar
Arc Bar
Generic Arc Bar

All non-generic modes are tied to the health/energy values of the client. The generic modes allow you to tie it to any thing you want. The Image an Arc modes allow you to specify a texture to use for the bar. No more plain old bars. The texture can even be animated by using a DML file and up to 30 image files representing the animation. There are even script events called on frame changes so you could play a sound such as a heartbeat. In the image below two guiAdvBarHuds have been added. The first is the beer mug. The texture animation is used to make the bubbles rise to the top. The second is the semi circle wich is also using a texture animation to count from 1 to 10 in a loop. There are a lot of possibilities with this control, digital dashboards for your racing game is another example.
