Reading a Transformation

Given a transformation (i.e. an XSLT object), its contents can be read and written to the console as follows:

Sample Code:

"! Code sample for reading the contents of a transformation (XSLT object).

"! IMPORTANT: The value of the constant CO_TRANSFORMATION_NAME must be replaced with
"! the name of an existing transformation for which the content shall be read.
