Nested Element Summary
	`admissiblePaths` Defines the set of admissible paths for a demand.
	`demandValue` This parameter value is interpreted for a specific demand such that at least routingUnit times demandValue many units must be routed through the network during normal operation (where all network components are active).
`xs:positiveInteger`	`maxPathLength` The maximum number of links used on a path to route this demand.
`xs:positiveInteger`	`routingUnit` The individual routing unit of this demand.
`globals:identifier`	`source` The identifier of the source node.
`globals:identifier`	`target` The identifier of the source node.

Attribute Summary
`globals:identifier`	`id` The identifier of the demand, which must be unique within all the demands.
