4 +
5 +The scope of this section is to define both best practices and mandatory behaviour for specific aspects of transformation between different versions of SDMX.

7 +== 11.2 Compatibility and new DSD features ==
8 +
9 +The following table provides an overview of the backwards compatibility between SDMX 3.0 and 2.1.
10 +
11 +|**SDMX 3.0 feature**|**SDMX 2.1 compatibility**|**Comments**
12 +|Multiple Measures|(((
13 +Create a Measure Dimension Or
14 +
15 +Model Measures as Attributes
16 +)))|For a Measure Dimensions, all Concepts must reside in the same Concept Scheme
17 +|Arrays for values|Cannot be supported|Arrays are always reported in a verbose format, even if one value is reported
18 +|Measure Relationship|Can be ignored, as it does not affect dataset format|
19 +|Metadata Attributes|Can be created as Data Attributes|Not for extended facets
20 +|Multilingual Components|Cannot be supported|
21 +|No Measure|Can only be emulated by ignoring the Primary Measure value|
22 +|Use extended Codelist|A new Codelist with all Codes must be created|
23 +|Sentinel values|Cannot be supported in the DSD|Rules may be supported outside the DSD, in bilateral agreements
24 +
25 +The following table illustrates forward compatibility issues from SDMX 2.1 to 3.0.

29 +Create a Dimension with role ‘MEASURE’
30 +
31 +Or
