I try to test an example, metamodel is generated from schema using EMF
facilities
<?xml version="1.0" encoding="UTF-8"?>

<complexType name="Product">
<sequence>
<element name="name" type="xsd:string" />
<element ref="ns:person" minOccurs="0" maxOccurs="1" />
</sequence>
</complexType>
<element name="person" type="ns:Person" abstract="true" />
<complexType name="Person" />
<element name="author" type="ns:Author" substitutionGroup="ns:person" />
<complexType name="Author">

<sequence>
<element name="name" type="xsd:string" />
<element name="mail" type="xsd:string" />
</sequence>
</extension>
</complexContent>
</complexType>
</schema>
transform model (product.xml) to itsslef.
<Product xmlns="http://www.m2matl.com/product"

<!--<person xsi:type="Author"> -->
<person xsi:type="ns:Author">

</Product>
when atl engineer(AtlEMFModelHandler) load this model,throw exceptions as
below:

I traced the problem in debug model, find that the product's metamodel is
load suceessfully, when load product.xml as a model it occurs the problem.
I ever use the schema generate product.genmodel product.ecore file ,using
EMF generate three plugin project: product,product.edit and
product.editor. The plugin works well and can create Product model
files(In this file,it doestn't container "person" element but "author"
element). But when the ecore file using in ATL,it has some problems.
Please help me,how to resolve the problem, and how to transform elements
having realtionship of "extend", can anyone give an example using
product.xml(maybe the product.xml need change) I list above tranform to
itself, any help would be appreciated very much!
Thanks in andvance!

Hello,
Can you please give us the listing of the metamodel that is generated
from your schema?
Your product.xml file should indeed conform to this metamodel, not to
the schema. Depending on how the translation was performed, the actual
metamodel may take very different forms.
Regards,
Frédéric Jouault
