Using Xerces 2.4,
My
intension is to define a unique key from the PickData
level. Should
Keys are
Pick/pickObsNo
Pick/DataSrc/id or Pick/DataSrcRef/id
Pick/VcPickSurfName/pickSurfName
Parser fails;
complains my constraint failed. If I have a DataSrc in one Pick and a DataSrcRef
in the other.
Parser Error: Not
enough values specified for <key name="Pick_InHierarchy_Key_Definition">
identity constraint specified for element "PickData".
If I have a DataSrc in both Picks, all is ok.
Is the "|"
an or ?
Can I use the "|"
in this way.
