Hi,
As the title of this book clearly states, this book teaches readers how to develop components. A component by definition must be reusable. The keywords here are components and reusability. You can't use containing elements such as html in a user control if you're designing the user control to be a reusable component where it is required to merge with different types of hosting pages without conflicts.

Sure if you don't want your user control to be a reusable component, you can include elements such as html.

Cheers!
Shahram
