After digging up the posts I decided to ask..

According to XML-RPC spec, parameter value of <string> cannot contain < or &.
This means, sending XML as a parameter should be escaped. Even though, it is
going to be part of another XML. Am I right?

Is there any way to keep XML in parameters un-encoded.. and so human readable?
eg. <xml> value "type"?

Maybe, I've gone too far. Please, clarify me either how to pass XML as a
parameter value or XML-RPC is not for this use and I must crack down to simpler
parameters or encoded (xml or base64) values.

Thank you
