In an XSD i have xsd:element declaration which have not type defined e.g.:FR_SM_CH and other having conplex type e.g. : FR_TP_CH
See the example
<xs:sequence>
<xs:element name="FR_SM_CH" minOccurs="0"/>
<xs:element name="FR_TP_CH" minOccurs="0">
<xs:complexType>
<xs:sequence>
<xs:element name="FR_TP_CHANNEL" minOccurs="0" maxOccurs="unbounded">
During the Ecore genration XsdEcoreBuilder maps as followning
<eStructuralFeatures xsi:type="ecore:EReference" name="fRSMCH" eType="ecore:EClass http://www.eclipse.org/emf/2002/Ecore#//EObject"
containment="true" resolveProxies="false">
<eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
<details key="kind" value="element"/>
<details key="name" value="FR_SM_CH"/>
<details key="namespace" value="##targetNamespace"/>
</eAnnotations>
</eStructuralFeatures>
<eStructuralFeatures xsi:type="ecore:EReference" name="fRTPCH" eType="#//FRTPCHType"
containment="true" resolveProxies="false">
<eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
<details key="kind" value="element"/>
<details key="name" value="FR_TP_CH"/>
<details key="namespace" value="##targetNamespace"/>
</eAnnotations>
</eStructuralFeatures>
Now when i use the Using the EcoreREflective Editor, the popup menu Create NewChild is populated correctly for the XSD Element having a complex type but for the xsd:element having no type,
the corresponding subMenu is repeated many time while i would expect it only one
I don't know why? Does anybody already encountered that problem ?
Thank you in advance
Philippe

Exactly.

Yes that would do the trick. Of course such an object is kind of
pointless because it doesn't carry any data, but then I'm not sure the
intent of the original schema... What is the point of this element if
not to carry arbitrary complex type instances?

If you're really intent on doing that, i.e.,I'm not sure the point/goal;
you can of course change the schema exactly as you've show it. Of
course you can use the debugger to see how your example above is
processed and what's produced for it verses the original form, i.e.,
look at what happens in
org.eclipse.xsd.ecore.XSDEcoreBuilder.createFeature(EClass,
XSDElementDeclaration, String, XSDComponent, int, int).

Hello Ed,
I come back to my problem with XSD which i let for a while.
In fact now i would like to identify all elements in my XSD files which have neither simple type nor complex type definition e.g. : <xs:element name="FR_SM_CH" minOccurs="0"/> : yes it doesn't carry any data
How can i find such elements ?
During my test, i expected that the returned type of such element would have been null !
XSDTypeDefinition elementTypeDefinition = getEffectiveTypeDefinition(xsdComponent, xsdElementDeclaration)
here is what i get : org.eclipse.xsd.impl.XSDComplexTypeDefinitionImpl@415262a0 (element: [xs:complexType: null]) (name: anyType, targetNamespace: http://www.w3.org/2001/XMLSchema) (derivationMethod: <unset>, final: [], abstract: <unset>, contentTypeCategory: elementOnly, prohibitedSubstitutions: [extension, restriction], lexicalFinal: null, block: null, mixed: true)

Yes, the absence of a type attribute in the concrete model for an
element declaration is defined in the specification to be equivalent to
specifying "xsd:anyType" explicitly.
XSDUtil.isAnyType can be used to check if a type represents the anyType...
