Schema (XSD) rule precedence

[Adam Flinton <adam.flinton@nhs.net>]

Dear All,

If I have a container element such as :

            <xs:all minOccurs="0">
                <xs:element ref="a" />
                <xs:element ref="b" />
                <xs:element ref="c" />
                <xs:element ref="d" />
            </xs:all>


And then a given element in the container has a minOccurs e.g.

  <xs:element minOccurs="1" name="a"/>

If I am walking a schema creating all required elements, do I create an
element <a/> or not?

i.e. what is the rule on constraints (e.g. required vs optional) in a
hierarchy?

TIA

Adam
