The default theme of CS2007/Chameleon uses ASP.net master pages, but the theme developer has complete control over how master pages (or the type of master pages) are used.
An MSDN-style downloaded compiled-help file has been created that includes documentation for all of the Chameleon controls in CS2007. Go to the Chameleon Control Documentation area of this site for more information.
The available properties and their data types are listed within the Chameleon Control Documentation area of this site.
