AXI WR_STRB=0's when WVALID =1.

In AXI, how does the slave interpret WR_STRB=0's when WVALID =1.

Agreed it is not common for the master to generate it. Not sure if this is a bug or should my slave be smart enough to detect this case and ignore data?

Did not find much description on this case on AXI spec.

Thanks
