constraint

From Architecture of the World Wide Web, Volume One (2004-12-15) | Glossary for this source

In the design of the Web, some choices, like the names of the p and li elements in HTML, the choice of the colon (:) character in URIs, or grouping bits into eight-bit units (octets), are somewhat arbitrary; if paragraph had been chosen instead of p or asterisk (*) instead of colon, the large-scale result would, most likely, have been the same. This document focuses on more fundamental design choices: design choices that lead to constraints, i.e., restrictions in behavior or interaction within the system. Constraints may be imposed for technical, policy, or other reasons to achieve desirable properties in the system, such as accessibility, global scope, relative ease of evolution, efficiency, and dynamic extensibility.
