Test of #IF

This document contains a simple demonstration of the #IF XSSI conditional server side include.

Note: the following #SET variables are equal to:

Begin the test ....
Samples Mode (SAMPLE_TYPE and SUB_MODE1):
   Sample_type=1 (SUB_MODE1 ignored)
End of test ....

Some explicit comparisons:
