A question about XML Schema in Web services

[Rahul Ba]

I have already put this question in XML certification forum on Javaranch, but did not get the answer hence, re-writing here.

  
   <types>  
   <schema targetNamespace="htp://abc.xyz/types"   
   xmlns:tns="http://abc.xyz/types"  
   xmlns:xsd="http://www.w3.org/2001/XMLSchema">  
    
   <xsd:complexType name="city">  
       <xsd:all>  
          <!-- Insert here -->  
       </xsd:all>  
    
    </xsd:complexType>  
  </types>  
  

Which two element definition when inserted in the given
comment result to the correct schema type defination.


A. <xsd:element name="f" type="xsd:string">
B. <xsd:element name="i" type="xsd:long" maxoccurs="5">
C. <xsd:element name="l" type="xsd:string" mioccurs="1" maxoccurs="5">
D. <xsd:element name="f" type="xsd:string" mioccurs="0" maxoccurs="5">


What is the answer....I am confused..if there is any document links that provide me ability of solving questions.

Thanks,
Rahul

Hi!
Please correct me if I am wrong, but as far as I understand, the use of <xsd:all> implies that all elements inside of the <xsd:all> has minOccurs=0 or 1 and maxOccurs=1.
This causes all alternatives you have supplied, except for alternative A, to become disqualified.
