+/**
+This 8-bit variable is used in CApaSisxRecognizer. Its default value is zero.
+It is used to override the default behaviour, i.e. recognise .sis file 
+extention and set iConfidence to ECertain; all other extensions will set 
+iConfidence to EPossible.
+If KSisxRecognizerConst is set to non-zero, CApaSisxRecognizer would set 
+iConfidence to ECertain for .sis, EPossible for .sisx and ENotRecognized for 
+all other extensions.
+
+This variable can be changed at ROM build time using the patchdata obey keyword.
+See Symbian OS Developer Library documentation on how to patch DLL data exports.
