the usage of WSTRB signal

Hi All,
I was going through the AMBA AXI specs, but I have some questions about the usage of the WSTRB signal. In the middle of a burst, can some bits of WSTRB be low? Again, in the last transfer of a burst, can some bits of WSTRB be low? For example, assuming the data bus is 32-bit wide and in the middle of a burst, can I transfer data 0x11xx22xx(x means don't care) and set  WSTRB to be 0b1010 ? Thanks in advance.
