UML22 — Section: 17.2.1

Typo - Change first sent. under sub-section Description to "...one or more information items circulates from its sources to its targets." Subject of phrase is singular (one or more) and needs the singular verb. Add OCL notation to the constraints or state that OCL notation is not available. Constraint [1] reads like an enumeration. Why is it not diagrammed showing an enumeration. Reword the except clause to "...and InstanceSpecification except when the classifier of the InstanceSpecification is a relationship (i.e., it represents a link)." Constraint [2] change "target" to "targets" and delete the prepositional phrase "if any." (Or explain how information can flow if there isn't at least one source and one target.)
