Overview of the Physical User Interface Layer
The physical user interface layer includes physical files, such as templates, Siebel tags, style sheets, and other metadata. These files and metadata control the layout and the look and feel of the Siebel client. The physical user interface layer separates definitions for style and layout from user interface objects that reside in the Siebel repository. This separation allows you to define style and layout across multiple objects of the Siebel client. For more information, see Siebel Developer's Reference.
