Profile

  • A profile holds a set of constraints.
  • A profile is itself a document.

Constraint

  • A constraint is a requirement a document satisfies or violates.
  • A constraint is expressed as XPath location path together with needed properties.
  • Within the context of a document, a constraint builds validators.

Validation Gate

  • A validation gate holds a set of constraint types and serves as validation executor.
  • A constraint is ignored if its constraint type is not part of the validation gate.
  • CMV defines four, hierarchically structured validation gates: Basic, Standard, Extended and Strict.

Validator

  • A validator is called by a validation gate to answer the question if the underlying constraint is satisfied or violated.
