To support advanced displays, a new XML object allows the use of color PNG images in addition to the grayscale

<URL> tag points to the PNG image file.
Cisco recommends that developers verify that their existing applications conform to the XML schema to avoid incompatibilities with any XML enhancements, particularly if you want to incorporate new URIs.
