By default oXygen performs ID checking and the error is related with that.
For each pair element-attribute it is defined an ID-type for the 
attribute value. That can be null, ID, IDREF or IDREFS. If there are 
cases when the schema allows different ID-type values for the same 
element-attribute pair then we have an error. Note that the 
element-attribute pair can be defined also with "wildcard" nameclases 
like anyName or nsName.
For details see [1].

You can disable the ID checking in oXygen from Options->Preferences -- 
XML -- XML Parser -- Relax NG / Check ID/IDREF

especially last point from:
***
A RELAX NG schema is compatible with this feature if and only if, after 
schema simplification, for each data or value element that specifies a 
datatype associated with a non-null ID-type, all of the following hold:

     * its parent is an attribute element
     * the first child of its attribute parent is a name element
     * the first child of the element ancestor is a name element
     * if its attribute parent has any competing attribute elements, 
then each such competing attribute element has a data or value child 
specifying a datatype associated with the same ID-type. Two attribute 
elements

       <attribute> nc1 p1 </attribute>

       and

       <attribute> nc2 p2 </attribute>

       compete if and only if the containing definitions compete and 
there is a name n that belongs to both nc1 and nc2. Note that a 
definition competes with itself.

Best Regards,
