How does a cascading style sheet allow the analyst to produce XML output?

What will be an ideal response?

Cascading style sheets are an easy way to transform an XML document. The style sheet provides a series of styles, such as font family, size, color, border, and so on, that are linked to the elements of the XML document. These styles may vary for different media, such as a screen, printed output, or a handheld device. The transforming software detects the type of device and applies the correct styles to control the output.
