The Element Notes Tab

The Element Notes tab in the Extension Taxonomies pane of the CDM Extension Taxonomy Editor displays the properties of an element that has possible replacement elements identified with it (alternate elements), that are included in the definition linkbase, and has a relationship to the possible replacement element (with custom arcrole).

The Element Notes tab displays alternate elements defined in the following definition linkbase: http://xbrl.fasb.org/us-gaap/2017/elts/us-gaap-tin-def-2017-01-31.xml. The content of this linkbase includes:

• All arcs are of the arc role type: alt-concept-supersededConceptForPeriodOfAndAfterAdoption.
• The source element (in effect, from part of the arc) is the element you select and use in the Primary Items pane.
• The target element (in effect, the part of the arc) is what is displayed in the Element Notes tab.

Because they are defined in a base definition linkbase or linkbases, the properties displayed on the tab are read-only and cannot be changed.

The labels shown in the Element Notes tab are labels of the selected Alternate Element, not the selected Element. Selecting a different element in the Alternate Element Name drop-down list changes the labels on this tab.

Note: The Element Notes tab is derived from the inclusion of the Taxonomy Implementation Note in US-GAAP 2016. However, any extension taxonomy using a similar definition linkbase structure can make use of this feature.

Options

• Alternate Element Name
  The name of the alternate element related to the element selected in the Primary Items pane.
• Alternate Element ID
  The ID of the alternate element and used to refer to the element in other documents (for example, linkbases).
• Arc Role URI
  The arc role URI of the alternate element.

The Labels Subtab

The Labels subtab is used to manage the labels that are present on the selected element. Elements can have multiple labels, and for each label, the language and type of label must be identified.

• Label Text
  The human-readable text to be displayed for the label.
• Label Type
  Indicates the circumstances in which an element is used, and how it displays in the presentation.
• Label Icon
  If a base label is non-discoverable, the Non-Discoverable icon displays with the label type. The label displays in supplemental linkbases only.
• Language
  The language of the label.
• Bind To Cell
  Used to create a permanent association between the label text and the text in a report object. When the text in the object changes, the label text also changes. If a label is bound, the Checkmark icon is displayed in the column.
• Prohibited
  Used to prohibit a base element label so that it is not available in the extended taxonomy. If a label is prohibited, the Prohibited icon is displayed in the column.

You can use the following icon in the icon panel to manage labels on the Label subtab.

The References Subtab

The References subtab displays references to authoritative definitions of the concept that is represented by the element. These definitions can be an accounting policy, rule, or regulation.
