grouping of properties via choice and/or sequence

[Ajay Aggarwal]

SchemaType.getElementProperties() return all possible properties for a
type. What is the easiest recommended way to find their
grouping/relationship? For example some of these may belong to a
'choice' particle. 

 

Is walking the particle tree the only option to find these
relationships?

 

For example, on the following type 'foo', getElementProperties() will
return {A, B, C, D, E, F, G}. How do I know that after property 'A' you
can either have {B, C} or {D, E, F, G}?

 

<xsd:complexType name="foo">

    <xsd:sequence>

        <xsd:element name="A" type="..." />

        <xsd:choice>

             <xsd:sequence>

                  <xsd:element name="B" type="..."/>

                  <xsd:element name="C" type="..."/>

             </xsd:sequence>

             <xsd:sequence>

                  <xsd:element name="D" type="..."/>

                  <xsd:element name="E" type="..."/>

                  <xsd:element name="F" type="..."/>

                  <xsd:element name="G" type="..."/>

             </xsd:sequence>

        </xsd:choice>

      </xsd:sequence>

  </xsd:complexType>
