You are asked to create an XML schema for a Postal service that accepts an address and returns the corresponding postal code. You are given the following specific instructions as to how the XML schema should be designed:
* The XML schema requires two elements named "PostalCodeLookup" and "PostalCodeResponse".
* The "PostalCodeLookup" element must contain child elements named "address1", "address2," "city", "stateOrRegion" and "country", in that order. Each of these elements must have the type string.
* The "PostalCodeResponse" element must contain only the postal code as a string and this element must not have any child elements.
Which of the following XML schemas fulfills the requirements while also following the instructions?

Wait, does "PostalCodeResponse" really need to be a single string? Seems too simple.

I’m not entirely confident, but I believe the order of the elements is crucial here, and I hope I remember it correctly from our last practice session.

I feel like I’ve seen an example where the response element had to be a simple type, so I think "PostalCodeResponse" should just be a string without any children.

I think the "PostalCodeLookup" should definitely have all those child elements, but I’m a bit confused about how to define them as strings in the schema.
