<tbx:definition> Definition (TBX)

A definition is a textual description of the concept behind the term entry. Each term entry must have one, and only one, definition. The principles in ISO 704 - Terminology work - Principles and methods should be followed in writing definitions.

Usage/Remarks

A TBX definition can contain lists, tables, other special markup, and certain symbols (those that can be expressed in a markup language such as MathML or via characters accessible from the keyboard).
A TBX definition can also include a term which is defined elsewhere in the standard. Such terms are called “entailed terms” and they must be enclosed in the <tbx:entailedTerm> element so that a link can be generated to point to the location where the definition of that term can be found.
