Re: How to get minOccurs and maxOccurs values from Element Declarations

Hi Stella,

You're asking for something you can't get.

Consider that one element declaration could be used in multiple places:

<xs:element name="foo" type="xs:string"/>
<xs:complexType name="bar">
 <xs:sequence>
  ...
  <xs:element ref="foo" minOccurs="2" maxOccurs="4"/>
 </xs:sequence>
</xs:complexType>
<xs:complexType name="baz">
 <xs:sequence>
  ...
  <xs:element ref="foo" minOccurs="3" maxOccurs="5"/>
 </xs:sequence>
</xs:complexType>

It's the particle (i.e. the usage of the element declaration) [1] which
holds the occurrence information not the element declaration itself.

Thanks.
