XML Conversions

Automatic conversion for XML is done if the attribute and the corresponding attribute implementation have primitive data type ‘anyType’. The attribute implementation must then have a ‘long’ domain as its native data type, which refers to an in-memory XML structure.

For an ‘anyType’, a hook must always be implemented. Mapping the attribute implementation directly to a table column will fail. In that case, when setting or changing the value, the column value will be the number that used to be the reference to the xml structure, but the actual xml structure will be lost.
