   * The first part ("info") simply contains some information what the test case \
does.  
-  * The second part ("fo") contains a full XSL-FO document.
+  * The second part ("variables") is optional and can contain variable definitions \
for the FO document if you want to avoid a lot of copy/paste. To refer to the \
variable "img" write "##img" in any attribute inside the FO document (see example \
above). The variable substitution is done using XSLT.  
+  * The third part ("fo") contains a full XSL-FO document.
+ 
-  * The third part ("checks") contains all the checks for this test. See below for \
details. +  * The fourth part ("checks") contains all the checks for this test. See \
below for details.  
  Now, when you are creating a test case you can use the XSLT stylesheet called \
"testcase2fo.xsl" if you want to manually run it through FOP (or any other XSL-FO \
implementation). The stylesheet basically extracts the XSL-FO document from the XML \
file.  
  When the JUnit checks for the layout engine are run, the following happens. The \
checks are extracted from the XML file and each of them is checked against the result \
from a FOP processing run. Most tests will check against the "Area Tree XML" that is \
generated by FOP's XMLRenderer. From the command-line you can access it if you use \
"-at" instead of "-pdf", for example. + 
+ When you run test cases the generated Area Tree XML is written to the \
{{{build/test-results/layoutengine}}} directory.
