+System version 0.5. It has also been called Karl's Templates,
+the Dynamic Publishing System (DPS), and Stencil. The official
+package name for the system is now

The template system is designed to be used by two classes of users: programmers and designers. In bulding a web site, programmers are generally responsible for defining and implementing -the application logic of the site, while designers are more -responsible for the presentation. Generally speaking, the -application logic generates data for the presentation to display to -the user. The template system must provide mechanisms that supports -both of these tasks and allows the designer and programmer to work -seperately, but for their work to be combined at runtime into -something that the user sees as a single page.

It must be easy to use/integrate the templating system with any application. This implies a stable, simple, and comprehensive API for programmers to use when writing or converting modules.
Programmers must be able to publish a page's data sources, so -that a graphic designer knows what data sources are available.

It must be simple for graphic designers to create and maintain templates that include dynamic data, and other templates. This requires a stable, simple, and comprehensive API for graphic designers to use when creating the layout pages for a site.
Much like the "mail merge" feature of a word processor, template -authors must use special tags to position each piece of dynamic -data within the layout. Each template is associated with a data -dictionary that lists all available variables.
10.10.2 Use of ComponentsTo speed development and ensure consistency of design, template -authors are encouraged to assemble pages from distinct component -templates that may be recycled in different contexts. One -typical practice is to build a "master" template for an entire -section of a site, with a common header, footer and sidebar layout. -For each page request, the "content" template is incorporated -dynamically into a specified area of the master template, usually a -table cell.

10.10.3 Inter-Template CommunicationTemplate authors need a simple mechanism for declaring properties within templates. The most common use of such properties is for configuring elements of an enclosing master template, such as the title, navigation links, and whether to include a search box.
10.10.4 Conditional InsertionDesigners often need to tailor the layout depending on the specific data being presented. For example, when presenting a list of library books that a user has checked out, the designer might want to highlight the overdue ones in red. For this, designers must -have the ability to write simple program logic (Note: We run the -risk of inventing our own language here, we must be +have the ability to write simple program logic (Note: We run +the risk of inventing our own language here, we must be careful).
