(shown in Figure 2) with keywords annotation of Statue of Liberty, Sea, Clouds,

that the same image is represented in an XML format.
Note that the XML representation of the image can conform to any domain-specific
XML schema. For the sake of illustration, consider the XML schema and the
corresponding XML representation of the image shown in Figure 3. This XML
schema stores foreground and background object information along with other
meta-information with keywords along various paths of the XML file.
