The Element Properties Tab

The Element Properties tab in the Extension Taxonomies pane of the CDM Extension Taxonomy Editor displays the properties of an element that is selected and highlighted in the Primary Items pane or Dimensions pane.

Options

• Name
  The name of the element that defines the concept within the taxonomy and instance document. For US GAAP extensions, the name must be unique, and it must follow the Label Camel Case Concatenation (LC3) rules for the SEC.
• ID
  The identifier for the element. It is used to refer to the element in other documents (for example, linkbases). The ID is in the form {Prefix}_{Name}, where {Prefix} is the taxonomy prefix, and {Name} is the element name. The ID field is read-only.
• Balance
  Used to assign the balance attribute of an element for calculation relationships.

  Table 1. Icons describing element balance

  Icon	Name	Description
  	Credit	The element has a balance attribute of (-1).
  	Debit	The element has a balance attribute of (+1).
  	Undefined	The element has no balance attribute assigned.

• Period Type
  Defines the period type of the element, either measured at an instant in time (for example, account balance) or measured over a duration of time (for example, total deposits).

  Table 2. Icons describing element period type

  Icon	Name	Description
  	Instant	An instant in time (for example, as of December 31, 2009).
  	Duration	A duration of time (for example, period of January 1 - December 31, 2009).

• Type
  The type of data that can be tagged to the element.

  The following table lists the most commonly used types that are derived from the standard (xbrli) taxonomy.

  Icon	Name	Description
  	String	Used for values that contain text, and can be mixed with numbers.
  	Monetary	Used for values that are expressed in units of currency.
  	Boolean	Used for values that are either true or false.
  	Decimal	Used for numeric values.
  	Integer	Used for numeric integer values.
  	G Year Month	Used for expressing a year and a month in the Gregorian calendar format YYYY-MM.
  	G Month Day	Used for expressing a month and a day in the Gregorian calendar format MM-DD.
  	G Day	Used for expressing a day in the Gregorian calendar format DD.
  	G Month	Used for expressing a month in the format MM.
  	Date	Used for expressing the date in the format YYYY-MM-DD.

• Abstract
  When this checkbox is selected, the element cannot be used to tag data. The labels of abstract elements are italicized in the Primary Items pane and the Dimensions pane. An abstract element cannot be used to tag data in an instance document.

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. The following table lists some frequent used icons, as examples.

  Table 4. Icons describing label type

  Icon	Name	Description
  	Axis Default	Used to display the preselected dimension member that is used as the default value.
  	Definition Guidance	Used to define a concept, including an explanation of the concept meaning and appropriate usage.
  	Disclosure Guidance	Used to define a concept disclosure requirement.
  	Documentation	Used to provide an element definition.
  	Label	The standard default label.
  	Measurement Guidance	Used to explain the methods that are required to measure values that are associated with a concept.
  	Negated	Used for labels that present values with reversed sign.
  	Negated Period End	Used for labels that presenting values that are associated with the end of a period, with a reversed sign.
  	Negated Period Start	Used for labels that present values that are associated with the start of a period, with a reversed sign.
  	Negated Terse	Terse label for presenting values with reversed sign.
  	Negated Total	Used for labels that present values with reversed sign, on elements that have a total value.
  	Negative	Used for reversing a value's weighting in the presentation linkbase.
  	Negative Terse	Terse label for reversing a value's weighting in the presentation linkbase.
  	Negative Verbose	Verbose label for reversing a value's weighting in the presentation linkbase.
  	Period End	Used for labels that present values associated with the end of a rollforward.
  	Period Start	Used for labels that present values that are associated with the beginning of a rollforward.
  	Positive	Used to indicate whether the value presented is positive (negative, zero). For example, the standard and standard positive labels might be "profit after tax"; the standard negative labels might be "loss after tax"; the terse label and terse positive labels might both be "profit"; and the negative terse label might be "loss".
  	Positive Terse	Terse label to indicate whether the value presented is positive (negative, zero).
  	Positive Verbose	Verbose label to indicate whether the value presented is positive (negative, zero).
  	Presentation Guidance	Used to explain the rules that regard presentation of a concept that is related to other concepts.
  	Terse	Used for short labels.
  	Total	Used for labels on elements that have a total value.
  	Verbose	Used for extended labels that give an exact description.
  	Zero	Used for a concept when the value of the concept is negative.
  	Zero Terse	Terse label that is used for a concept when the value of the concept is negative.
  	Zero Verbose	Verbose label that is used for a concept when the value of the concept is negative.

• 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 icons in the icon panel to manage labels on the Label subtab.

The References Subtab

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