Ejemplo: <constraintSpec> (constraint on schema)
These search results reproduce every example of the use of <constraintSpec> 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 <constraintSpec> 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.
