XML Schema import question

[Guillaume]

Hi,

I'm importing separate XSD files with a number of complexTypes.
They all belong to the same namespace test1.

In tst_ElementC.xsd, tst_ElementC_2 complex type has an element of type test1:tst_ElementC_1, which is declared in the same XSD file.
Result in EA: an association is created between tst_ElementC_1 & tst_ElementC_2. -> expected result (OK)

In tst_ElementC.xsd, tst_ElementC_1 complex type has an element (elementA) of type test1:tst_ElementA, which declared in tst_ElementA.xsd.
Result in EA: elementA is declared as an attribute of tst_ElementC_1 which type is tst_ElementA -> I was expecting an association between tst_ElementC_1 and tst_ElementA.

Is there any way to achieve what I'm looking for, or is there a reason explaining why we're getting this?
Note that I chose the option to import XSD Elements/Attributes as UML Associations.

As a workaround I could define a script that will replace all attribute types with associations but this can be time consuming both for me and the users.
