Crash when loading XMP containing linked data rows.
SMPs and XMPs have the possibility to contain data rows, which don't contain data but are linked to other data rows. Besides the link details those links contain also calculation instructions, how the linked data row shall be calculated from the source data row.
Such computations will not be supported by the XML reader. For this advanced feature SIMIData has to be used.
But when loading XMPs with the XML reader, no exception shall be thrown. The linked data shall be simply ignored.
