Method Summary

protected boolean	accept(XSLTVisitor visitor) Accept a visitor and call the appropriate method for this class.
void	compose(StylesheetRoot sroot) This function is called after everything else has been recomposed, and allows the template to set remaining values that may be based on some other property that depends on recomposition.
void	execute(TransformerImpl transformer) Execute an extension.
void	executeFallbacks(TransformerImpl transformer) Execute the fallbacks when an extension is not available.
String	getAttribute(String rawName) Return the raw value of the attribute.
String	getAttribute(String rawName, org.w3c.dom.Node sourceNode, TransformerImpl transformer) Return the value of the attribute interpreted as an Attribute Value Template (in other words, you can use curly expressions such as href="http://{website}".
private ElemExtensionDecl	getElemExtensionDecl(StylesheetRoot stylesheet, String namespace) Return the ElemExtensionDecl for this extension element
int	getXSLToken() Get an int constant identifying the type of element.
boolean	hasFallbackChildren() Return true if this extension element has a child element.
