Direct Known Subclasses:
  StylesheetRoot

public class Stylesheet
extends UnImplNode
implements java.io.Serializable, org.w3c.dom.Document, PrefixResolver

Represents the base stylesheet or an "import" stylesheet; "include" stylesheets are combined with the including stylesheet. At the moment these stylesheets can not be reused within the stylesheet tree or between trees. This needs to be fixed in the future.

  Serialized Form
