Class: CSL::Style::Label

Inherits:
Node show all
Defined in:
lib/csl/style/label.rb

Overview

Labels are used for printing the term matching the variable selected with the required variable attribute, which must be set to “locator, ”page“, or one of the number variables.

The term is only rendered if the selected variable is non-empty.

If the Label is the child of a Names node, the parent’s variable is used instead of the local attribute.
