Specifying an SVG Pattern

Syntax: <overlay …>SVG-pattern</overlay>

Example:

<overlay rule="VERSION(@introduced) = VERSION()" label="New in {@ver}"> 
    <radialGradient gradientUnits="userSpaceOnUse" cx="10" cy="10" r="14"> … </radialGradient>
</overlay> 

Use: Creates a new pattern to use under specific criteria.

If the built-in patterns are not sufficient, new ones can be defined using SVG. The contents of <overlay> are a single SVG element defining a pattern. The pattern can also be defined in an <svg:defs> element and referenced in the <overlay> content.
