A style node exists within the Style Sheet and holds a collection of Style Attributes and Style Variants.

Any node added to the style node which has no children is loaded as a Style Attribute, whereas any child nodes with children are loaded as Style Variants. Style Variant nodes then have Style Attribute nodes as children to define the style of the variant.

A style node may use the "Base" attribute to define a base style to modify. For example; if the style "Pane" has been set up to act as a pane style, having the Base="Pane" attribute on the Button style will cause the Button style to copy Pane's data and any copied data within the Button style is simply overwritten.

<Pane>
    <SliceFrame Image="Pane"/>
    <Font Font="BasicFont"/>
    <Content Colour="#ff0"/>
</Pane>

<Button Base="Pane">
    <SliceFrame Tint="#ccc"/>
    <Content Colour="#000"/>
</Button>

Is equivalent to

<Button>
    <SliceFrame Image="Pane" Tint="#ccc"/>
    <Font Font="BasicFont"/>
    <Content Colour="#000"/>
</Button>
