Re: PSVI

You cannot get occurrence information from element decls, because that's
part of a particle, not part of the element decl.

To get such information, you need to start from the complex type definition
of "RequestVerb". You can call getParticle on such complex type to get it's
content (a particle). getTerm on such particle would return a model group
(a sequence). You can then get a list of particles from this model group.
Each of the particle in the list has information about min/maxOccurs and
its term (element declaration).

How to represent annotations is still an open issue of PSVI interface
design. Your opinion on this would be appreciated.

Hi

1. How can I get particle information from XSElementDeclaration for local
elements?

For example, in the below example, how can I find el2 has minOccurs=1 /
maxOccurs=10 and el3 has minOccurs=1 / maxOccurs=20

<xs:complexType name="RequestVerb">
  <xs:complexContent>
    <xs:extension base="ConfirmableVerb">
      <xs:sequence>
        <xs:element name="el2" type="xs:string" minOccurs="1"
maxOccurs="10"/>
        <xs:element name="el3" type="xs:string" minOccurs="1"
maxOccurs="20"/>
        <xs:element name="el4" type="xs:string"/>
        <xs:element name="el5" type="xs:string"/>
      </xs:sequence>
      <xs:attribute name="attr11" type="xs:string"/>
    </xs:extension>
  </xs:complexContent>
</xs:complexType>

2. What are the plans for parsing Annotations? Would there be capability
to parse the user defined annotations during schema parsing to avoid
having to parse in PSVI?

thanks
manish
