I meet a case when I do the schema testing, which as the following:



         <xs:complexType name="One">


                     <xs:element name="elem1" type="xs:string"

                     <xs:element name="elem1" type="xs:string"





There are two elements with the same name "elem1" and the same target

inside the <xs:sequence>. Is this allowed? 


I read the spec and get the description which says: 

3.15.6 Constraints on Schemas as a Whole  

Schema Component Constraint: Schema Properties Correct

2 Each of the {type definitions}
<http://www.w3.org/TR/xmlschema-1/#type_definitions#type_definitions> ,
{element declarations}
ions> , {attribute group definitions}
_group_definitions> , 

{model group definitions}
efinitions>  and {notation declarations}
ations>  must not contain two or more 

schema components with the same {name} and {target namespace}.


I think this case violate this rule. However, I test it with many schema
validation tools and get the report that

"This case is correct".  Someone can give me an answer about it? 


Thanks and Regards,
