Mở rộng XSLT là, theo định nghĩa, một cơ sở bên lề của đặc tả kỹ thuật. | node employee 1 employee 3 employee 2 employee 1 stack 1 2 2 2 match employee employee node employee 1 employee 3 employee 2 employee 1 employee 1 stack 1 2 2 2 3 match employee node employee 1 employee 3 employee 2 employee 1 stack 1 2 2 2 reportsTo node employee 1 employee 3 employee 2 employee 1 stack 1 2 2 2 HimHer node employee 1 employee 3 employee 2 employee 2 stack 1 2 2 2 match employee employee node employee 1 employee 3 employee 2 employee 2 employee 1 stack 1 2 2 2 3 match employee node employee 1 employee 3 employee 2 employee 2 employee 2 stack 1 2 2 2 3 match employee node employee 1 employee 3 employee 2 employee 2 stack 1 2 2 2 reportsTo node employee 1 employee 3 employee 2 employee 2 stack 1 2 2 2 HimHer node employee 1 employee 3 employee 2 employee 3 stack 1 2 2 2 match employee employee node employee 1 employee 3 employee 2 employee 3 employee 1 stack 1 2 2 2 3 match employee node employee 1 employee 3 employee 2 employee 3 stack 1 2 2 2 reportsTo node employee 1 employee 3 employee 2 employee 3 stack 1 2 2 2 HimHer node employee 1 employee 3 employee 2 stack 1 2 2 reportsTo node employee 1 employee 3 employee 2 stack 1 2 2 HimHer node employee 1 employee 3 stack 1 2 reportsTo node employee 1 employee 3 stack 1 2 HimHer node employee 1 stack 1 reportsTo node employee 1 stac k 1 HimHer The modified stylesheet outputs trace messages via the xsl message mechanism. The format for every processed node is as follows node XPath to this node stack call stack of the templates invoked param name parameter name value parameter value more parameters . variable name variable name value variable value more variables . The call stack takes the form of a path with as separator and includes all passed templates. If a template has a name attribute then this name is used.
