Creating data structure for XML/JSON from IWS

This is on a v7r3 LPAR. I had a working REST service to add data from a web form to a lab repair table. It worked fine. Then they wanted to add several lines of comments.  My thought was the XML would look like this:

 <case>
  <name>Customer Name</name>
   <addr1>123 Main St</addr1>
   <city>Springfield</city>
   <state>WK</state>
   <zip>12345</zip>
   <email>homers@xxxxxxxxxxx</email>
   <sku>A1234</sku>
   <proddesc>whatchamacallit</proddesc>
   <serialnbr></serialnbr>
   <phone>8005551212</phone>
   <comments>
       <line>line 1</line>
       <line>line 2</line>
   </comments>
 </case>

and the RPGLE data structure would look like this:

 d AddCase pr
 d  pCaseInfo                            const likeds(case)                 input
 d  pAddResult likeds(AddResult)                  output

 d case            ds                    qualified template
 d  name                         25a
 d  addr1                        25a
 d  addr2                        25a
 d  addr3                        25a
 d  city                         16a
 d  state                         2a
 d  zip                          10a
 d  email                       100a
 d  sku                          10a
 d  serialnbr                     8a
 d  proddesc                     30a
 d  phone                        10a
 d  comments                           likeds(commentlines)

 d commentlines    ds                    qualified template
 d  line_LENGTH                  10i 0
 d  line                         79a     dim(3)

I used IWS to create the web service and tested it. There are no errors, however, the comment "line" array is all blanks, although the line_LENGTH variable contains 3.

What is IWS doing that I don't understand?
