Here are some examples of issues that result due to conflicting schemas. 

example 1: id constraint conflict
---------------------------------

ID is simple-type in one schema and complex-type in another schema.

<element name="foo"> 
    <sequence> 
... ...
    </sequence> 
    <sml:key name="bar" > 
        <sml:selector xpath="deref(students)/student"/> 
        <sml:field xpath="ID"/> 
    </sml:keyref> 
</element> 


example 2: targetType conflict
------------------------------

doc1 uses xsd-v1 and doc2 uses xsd-v2.
There is a ref from doc1 to doc2. The ref has a targetType=FooType constraint
on it.
FooType definition is different in the 2 conflicting schemas.


<element name="RefElement1" sml:targetType="tns:FooType"/>
