Hi today i have found a error saying that some values are missing the que while monitoring .

To check the error i have tested the MM using inbound pay load but its throwing error like given below

The processing instruction target matching “[xX][mM][lL]” is not allowed.

I just want to know what could be the problem. and i also want to know if there is any other way to moniter message mapping errors and how to find out MM using xml payload.

Thanks in advance.
