Ecore genaration via xsd have some problems. [message #774172]

hi,

if I use ComplexType to describe element

 <xs:element name="property">
         <xs:complexType ecore:name="ConfigurationProperty">
              <xs:simpleContent>
                   <xs:extension base="xs:string">
                        <xs:attribute name="name" type="xs:string" use="required" />
                   </xs:extension>
              </xs:simpleContent>
         </xs:complexType>
     </xs:element>

generated Ecore contains entity like below.As a EClass.

If I use SimpleType to describe the element

 <xs:element name="description" minOccurs="0" maxOccurs="1">
		<xs:simpleType>

    		<xs:restriction base="xs:string"/>

		</xs:simpleType>
	   </xs:element>

EMF take it as EDataType

but if I use just element.

 <xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="1">

I can not refer that element generated ecore dose not contains only is as a attribute of the parent element.But i want it as a Entity as in the first picture because I am using EMFText for define some DSL but in the rule definition I can not refer those "elements" because they not have real reference in the .genmodle. what do i do for this.is some thing wrong with my usage.?

So the first approach is the one you should take. I.e., if you want an
EObject that holds the value, you have to use a complex type, not a
simple type.
