XSD Question maxOccurs="unbounded"

Question

I have generated an XSD file from an XML snippet using xsd.exe /out

What its done is created maxOccurs="unbounded" properties for certain elements.

If I only want the element to appear once, and not be a collection do I set the maxOccurs like this?

maxOccurs="1"

Thanks

Answer 1

Yes, that's how it's done.

maxOccurs limits the maximum number of repetitions of a given element that can appear.

Similarly, minOccurs limits the minimum number of repetitions.

They're called occurrence indicators. You can read more about them at W3Schools.

Answer 2

Yes. maxOccurs="unbounded" is actually the default, so you don't need it, but apparently xsd.exe feels like being thorough. Of course, keep in mind that maxOccurs is really maximum occurances - there can still be zero. If you want there to always be one, you'll need minOccurs="1" as well.
