RE: [xml-dev] minOccurs maxOccurs doesnt seem to be working correctly in my schema

[Marielou <marielou_h@yahoo.co.uk>]

So is the following expected to work out:
in element A, I have <all> elements occuring 0 or 1
times max:

<xs:element name="A">
<xs:complexType>
<xs:all>
<xs:element ref="progid" minOccurs="1" maxOccurs="1"/>
<xs:element ref="start" minOccurs="1" maxOccurs="1"/>
<xs:element ref="end" minOccurs="1" maxOccurs="1"/>
<xs:element ref="pil" minOccurs="0" maxOccurs="1"/>
...
<xs:element ref="B" minOccurs="0" maxOccurs="1"/>
</xs:all>
</xs:complexType>
</xs:element>

and the elements which need to be able to occur more
than once are referenced in A, but defined outside of
element A. e.g. element ref B has occurences defined
in element B where e.g. in a sequence in B the element
can have maxOccurs "unbounded":

<xs:element name="B">
 <xs:complexType>
  <xs:sequence>
   <xs:element ref="audio" minOccurs="0"
maxOccurs="unbounded"/>
  </xs:sequence>
 </xs:complexType>
</xs:element>

the element referenced in B is then also declared
separately e.g.

<xs:element name="audio">
<xs:simpleType>
<xs:restriction base="xs:decimal">
<xs:minInclusive value="0"/>
<xs:maxInclusive value="8"/>
</xs:restriction>
</xs:simpleType>
</xs:element>

Thanks!
