 Value:
 ======
-When the value is of type Index Position, you can left shift the value 4 times to get an offset into the Block Index. Some descriptor types can have Id2 values. This is recognised by using a bitwise AND with the number. ie val & 0x0000000F. if the result is 0xF, it is likely to be a Id2 reference.
