+It just works fine. So, at least you need a schema which exactly
+reproduce the issue, but I rather just close this NOTABUG issue as it
+is rather a bug in MS.
+
+Having duplicate IDs in a schema scope (schema set) should be regarded
+as invalid in System.Xml.Schema. Every other components than XmlSchema
+(i.e. XmlSchemaElement, XmlSchemaAttribute et.al.) are rejected when
+there is a duplicate ID.
+
+In XML Schema specification there is no mention on ID scope and schema
+set (ID in DTD is only scoped within a document), but since .NET
+rejects all other components but does not reject XmlSchema, it must be
+a bug due to the design.
