Hi,
what about something like this:
Fragment from schema:
<xs:simpleType name="RoleName">
<xs:restriction base="xs:string">
<xs:enumeration value="InfrastructureManager"/>
<xs:enumeration value="Operator"/>
<xs:enumeration value="Contractor"/>
<xs:enumeration value="Manufacturer"/>
</xs:restriction>
</xs:simpleType>
Usage in document:
<role id="001" roleName="InfrastructureManager" owner="BrokenTracks"
uic="foo"/>
<role id="002" roleName="Operator" owner="SpeedyRailways" uic="xxx"/>
<role id="003" roleName="Contractor" owner="AtYourServiceCorp" uic="yyy"/>
<role id="004" roleName="Manufacturer" owner="SteamCoach" />
....
<infraStructure>
....
<infraAttributes><roleref ref = "001" startdate="..." ... </infraAttributes>
....
</infraStructure>
<timetable>
....
<trainPart><roleRefs>002 003</roleRefs><trainPart>
....
</timetable>
<rollingStock>
<vehicle>
<classification>
<roleRefs>
<roleRef ref="004" startDate="..." .../>
...
</roleRefs>
</classification>
....
Regards,
Andreas Tanner.
