A system is described for building a dialog-related user interface presentation. The system includes description language content (such as markup language content) which describes different aspects of the dialog-related user interface presentation. The system also includes generic resource content for providing various general purpose user interface resources that can be used in different dialog-related user interface presentations. The system provides the specific dialog-related user interface presentation by combining the description language content and the generic resource content. In other words, the description language content effectively tailors the generic resource content to provide the specific dialog-related user interface presentation. One aspect of the description language content defines the type of the dialog-related user interface presentation that is to be deployed. Another aspect of the description language content describes a manner of arranging (or otherwise deploying) parts of the dialog-related user interface presentation. Another aspect of the description language content defines default content that is provided by the dialog-related user interface presentation. Another aspect of the description language content describes validation rules used to validate information input by a user via the dialog-related user interface presentation.
