<!-- This stylesheet extracts the FO part from the testcase so it can be passed to FOP for layout. -->
<!--
Variable substitution:
For any attribute value that starts with a "##" the stylesheet looks for an element with the variable
name under /testcase/variables, ex. "##img" looks for /testcase/variables/img and uses its element
value as subsitution value.
