Beispiel: <constraint> (constraint rules)
These search results reproduce every example of the use of <constraint> in the Guidelines, including all localised and translated versions. In some cases, the examples have been drawn from discussion of other elements in the Guidelines and illustrating the use of <constraint> is not the main focus of the passage in question. In other cases, examples may be direct translations of each other, and hence identical from the perspective of their encoding.
