What is the proper AVRO schema for XML that uses namespaces

[#1]

Hi.

I have XML data that contains namespaces. I would like to use a ConvertRecord processor to convert this to JSON (eliminating message types I dont need)

<ds:tfmDataService xmlns:ds="the:ds:namespace"
                   xmlns:fdm="the:fdm:namespace">
   <fltdOutput>

      <fdm:fltdMessage param1="param1_val"                        
                       param2="param2_val">     
      </fdm:fltdMessage>

      <fdm:fltaMessage param1="param1_val"
                       param2="param2_val">     
      </fdm:fltaMessage>

    </fltdOutput>
</ds:tfmDataService>

I need to convert these messages from XML to JSON. There are messages of different types (fdm:fltdMessage is one type, fdm:fltaMessage might be another type) The contents of fltdMessage is more complex than depicted, however I'm trying to reduce this to the simplest terms that I can build on.

What would the AVRO spec look like for an XMLReader, if I wanted to convert the <fdm:fltdMessages> to JSON, but ignore the other types?
