This graphic is explained in the accompanying text

Make the following settings for the properties of each context element:

Context element	Type	Attributes	Value
Customer	Value node	cardinality	0..n
Customer	Value node	singleton	true
Name	Value attribute	type	string
Address	Value node	cardinality	0..1
Address	Value node	singleton	false
Street	Value attribute	type	string
City	Value attribute	type	string
HouseNo	Value attribute	type	string
PostalCode	Value attribute	type	string
Country	Value attribute	type	string
Order	Value node	cardinality	0..n
		singleton	true
		supplyFunction
		We will add a supply function called supplyOrdersForCustomer later (refer to Adding a Supply Function).
Date	Value attribute	type	string
Product	Value attribute	type	string
Price	Value attribute	type	string
Currency	Value attribute	type	string

Remember that the singleton attribute for the context value node Address will be assigned the value false.
