XAML is an XML file that defines user interfaces. It not only defines the frames, buttons, fields but also introduces any other visual effect that the interface may require. In a similar way to Flash interfaces, XAML provides a rich user experience with a variety of graphical effects.
For example, you could define a button as follows:
This is a button
So what! How does this help the technical author? Here we find one of the best kept secrets of this new technology. Whilst its benefits for programmers and designers is often highlighted:
What is less publicised is how this opens up the development process to other players, such as the technical author. Not only does this help close the great divide between authors and devlopers, it also starts to provide a route to achieving the sort of user guidance offered by Assistance Platform.
Firstly, it becomes a possibility for the technical author to become the owner of all the text in the appication. The user interface text in the XAML files can easily be updated with little programming knowledge.
Sceondly, it also become possible to generate templates for dialog help, as the XAML can be transformed with an XSL to produce a XHTML page that lists all the fields and includes notes as the starting point of the help project.
Thirdly, the XAML itself can also be checked from a consistency perspective. An XSL file can run through the file checking it aganist the companies interface standards. Again this helps the technical author flag up any issues with the user interface.
We find that this helps, authors move towards providing more wide spread User Assistance than simple help files. Aspects of Vista, such as super tooltips, require much more integration between the help content and the application. XAML provides a means for us, technical authors, to play our part to achieve this.
