Hi,
I imported in EMF an XSD file with this part inside:
<xsd:complexType name=3D"vector">
<xsd:sequence>
<xsd:element name=3D"x" type=3D"xsd:double"/>
<xsd:element name=3D"y" type=3D"xsd:double"/>
<xsd:element name=3D"z" type=3D"xsd:double"/>
</xsd:sequence>
</xsd:complexType>
I worked on my model and then I exported again the data in XSD format =
(by "Generate Schema" function of genmodel).
I obtained this (regarding the part above):
<xsd:complexType name=3D"Vector">
<xsd:attribute name=3D"x" type=3D"xsd:string" use=3D"required"/>
<xsd:attribute name=3D"y" type=3D"xsd:string" use=3D"required"/>
<xsd:attribute name=3D"z" type=3D"xsd:string" use=3D"required"/>
</xsd:complexType>
the simple types "xsd:double" of my original XSD have been translated in =
"xsd:string",
and the original xsd:element name=3D"x".... have been translated into =
xsd:attribute.
To re-obtain the types "double" (and not "string"), I had to change in =
the ecore model the type of "x"... from Double into EDouble.
I have to change the elementaty types into ETypes for all my entities, =
or is there an easier way to obtain in output an XSD more adherent to =
the input one ?
Thanks a lot.
Best Regards.
Pietro

Pietro,
We are working on improved support that will take extended meta data
annotations into account and that will generate appropriate simple type
definitions:
93194 <https://bugs.eclipse.org/bugs/show_bug.cgi?id=93194>
The focus is on being able to round trip Ecore -> XSD ->Ecore. In
general XSD -> Ecore is somewhat lossy, so XSD -> Ecore -> XSD will
never be a perfect round trip in general (although it should be a good
round trip for the common simple case).
