Oslo Børs will make a minor change to the top level element of all XML reference data files.
The "validDate" attribute of the top level element of each file will be modified to contain the trading date for which the file is valid (i.e. the same date which is also included in the file name). Previously this attribute contained the file creation date. However, the file creation date can be found in the "generated" attribute of the same element. There is no change to the "generated" attribute.
The change will take effect in CDS from 27 June. We will announce the release date for production at a later date, after the summer freeze period.
