- 'DurationFormat' field was removed
- 'Value' field was removed
- 'AttributeType' field was added
- Following fields were added: 'DateValue', 'DurationValue', 'NumericValue', 'FlagValue', 'TextValue'.
The following table shows which field contains the value of extended attribute depending on ExtendedAttribute's type. Thus in order to get or set the value of a custom field with 'Date', 'Start' or 'Finish' type one should use 'DateValue' field.
