 Each code is a separate [[Item]] so must have an ID and a Name, but can also have an optional Description. While Code IDs must be unique within a Codelist, the same Code ID may be safely used in other Codelists. For instance: The code 'A' may be used in a <em>Frequency Codelist</em> to represent 'Annual', but also appear in an <em>Industry Codelist</em> to represent 'Agriculture'.<br>

Whereas observations for the same ‘GE’ code but for the period 2005 must relate to Georgia. Observations for country ‘GE’ during the period 1978 and 1990 will be rejected as invalid because the validity rule states that no country with that code existed between those dates.

 Codelist IDs are given a 'CL_' prefix to distinguish them from other structures. For instance: CL_FREQ, CL_REF_AREA, CL_AGE.
-==Code ID Conventions==
+</p>
 Codes can take any legal SDMX [[SDMX ID|ID]]. But there are several conventions that should be taken into account when choosing Code IDs:<br>
-{|
+{| class="wikitable"
-| <strong>Uppercase Code IDs</strong> || By convention, Code ID's are in uppercase such as 'ABC'. Lower case Codes are valid (for example 'abc'), but care should be taken in their use to avoid confusion.
+|-

 | <strong>'_Z' Code</strong> || The '_Z' code is conventionally used for the Undefined and Unknown classification.
@@ Line 109: / Line 114: @@
 | <strong>'TOTAL' Code</strong> || The 'TOTAL' code represents the total or sum of the dimension. For a 'country' dimension, series with TOTAL would indicate the sum of observation values for all countries.
