(topic concept)
The <concept> element is the top-level element for a topic that answers the question what is? Concepts provide background information that users must know before they can
successfully work with a product or interface. Often, a concept is an extended definition of a major abstraction such as a process or function. It might also have an example or a graphic,
but generally the structure of a concept is fairly simple. Category: Concept elements
The <conbody> element is the main body-level element for a concept. Like the <body> element of a general <topic>, <conbody> allows paragraphs, lists, and other
elements as well as sections and examples. But <conbody> has a constraint that a section or an example can be followed only by other sections or examples. Category: Concept
elements
The <conbodydiv> element is similar to the <bodydiv> element in that it provides an informal container for content that may be grouped within a concept. There are no
additional semantics attached to the conbodydiv element; it is purely a grouping element provided to help organize content.
