Element Definition Documents
At the heart of every FrameMaker application is an element definition document (EDD). An
EDD provides three types of information:
• The definitions of the elements that can occur in a document, including their allowable
content and attributes. These definitions can be automatically extracted from the DTD, if
there is one.
•
The formatting rules that define the visual characteristics of various document
components.
•
Other information governing behavior of elements, including rules for automatically
inserting several elements in response to a single user action, preparing for the use of
document fragments, and so forth.
Since an EDD is a structured document, the FrameMaker Guided Editing feature assists
developers in creating proper EDDs. In particular, developers need not remember where to
insert element definitions, context specifications, or format rules. The Structure View and
Element Catalog guide them in creating these constructs correctly. The formatting of the
EDD increases its readability: Different fields are clearly labeled, and spacing, indentation,
and different fonts emphasize its organization. Developers can increase the accessibility of
information by grouping element definitions into sections and explaining them with extensive
comments. These characteristics are illustrated by the following fragment:
