−  PURPOSE : Decoding of the BREAK_COND element. This element consists of a V 
+
−            component with a variable bit length and must be connected with a 
+
−            special condition. This condition has to be a simple value, which 
+
−            matches to the value range of BREAK_COND element itself.
+
−            This function performs a standard decoding for a given elem table
+
−            entry. This means for non structured elements that 1-n bits are
+
−            read from the bitstream and write to a C-Variable in a machine
+
−            dependent format.
+
−            After decoding of the requested number of bits the resulting value
+
−            will be compared with the constant given by the condition. In case
+
−            of equality the global variable globs->continue_array is set to 
+
−            FALSE. This breaks decoding of the current superior composition 
+
−            and finishes the array.
