Attribute: style ¶

Attribute: textFrameStyle ¶

Each of these refers to a style element. style is the style of the label text, textFrameStyle the style for the frame around the label.

Attribute: purpose ¶

The kind of entity being labeled.

A descriptionGroup concatenates one or more elements to form a label. Each element can be a text element, which contains literal text, or a description element that substitutes a value or a variable name.

Attribute: target ¶

The id of an element being described. In the corpus, this is always faceting.

Attribute: separator ¶

A string to separate the description of multiple groups, if the target has more than one. In the corpus, this is always a new-line.

Typical contents for a descriptionGroup are a value by itself:

<description name="value"/>

or a variable and its value, separated by a colon:

<description name="variable"/><text>:</text><description name="value"/>

A description is like a macro that expands to some property of the target of its parent descriptionGroup. The name attribute specifies the property.
