|Rule||A schema that defines concepts MUST have a linked 2.1 label linkbase A schema defining non-reportable concepts for the presentation hierarchy of tables MUST have a linked generic label linkbase.|
|Explanation||Each schema that creates XML nodes must provide the means to include these nodes correctly in a presentation. The XBRL specification provides a label linkbase to support such presentation. For each concept that can be reported in an instance a presentation label needs to be present for software suppliers. This rule, in cooperation with 2.02.02.26, makes sure that all instance nodes have presentable labels.|
|Error message||XML Schema's defining concept MUST have a linked 2.1 label linkbase XML Schema's defining non-reportable concepts for the presentation hierarchy of tables MUST have a linked generic label linkbase.|

Known irregularity in NT11: This is not the case if it is a non-reportable concept used in the presentation hierarchy of tables. In that case it has to have a generic link base. This rule will be adjusted for this in the NT12.
15/05/2017: the rule is adjusted for the known irregularity above.
