Variable parameters list in WSDL

I need to implement a WSDL interface (HTTP binding) for a variable list function. What I need to do is something very similar to a wrapper for an ipothetic WSDL export of a printf function, in example. The parameters that i'll receive will have both a name and a value, and they are both not known in advance. So an input message 开发者_开发问答could be like:

param1=value1

param2=value2

param3=value3

....

paramN=valueN

etc, and the name ("paramX"), the value ("valueX") and total number of parameters are not known. What is the best way to model this kind of function with WSDL?

Thank you!

Pass an array of objects, each consisting of a name and a value.
