Hi Dirk,

thanks for the input, I agree with you! As we have discussed in earlier
meetings and documented in the railML-Wiki
(https://wiki.railml.org/index.php?title=TT:train) a train should have
trainNumber, additionalTrainNum, scope and operating period as unique
key in railml.

Therefore I propose to add an element replacements with following schema
definition to the eTrain Element:

<xs:element name="replacements" type="tReplacedTrains">
</xs:element>



<xs:complexType name="tUniqueTrainKey">
<xs:sequence>
<xs:element ref="eOperatingPeriodRef"/>
</xs:sequence>
<xs:attributeGroup ref="aUniqueTrainKey"/>
</xs:complexType>
<xs:complexType name="tReplacedTrains">
<xs:sequence>
<xs:element name="replacementOf" type="tReplacementOf" minOccurs="0"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="tReplacementOf">
<xs:choice>
<xs:element ref="tafTapTsiTrainID"></xs:element>
<xs:element ref="eUniqueTrainKey"></xs:element>
</xs:choice>
</xs:complexType>
<xs:attributeGroup name="aUniqueTrainKey">
<xs:attribute name="trainNumber" type="xs:string"/>
<xs:attribute name="additionalTrainNumber" type="xs:string"/>
<xs:attribute name="scope" type="tTrainScope"/>
</xs:attributeGroup>
<xs:element name="eUniqueTrainKey" type="tUniqueTrainKey">
</xs:element>

Best regards,
Leo
