Hi again Sonalee,
I have heard back from Development today, and they state that the ability to add line-breaks in a WADL for auto-generated documentation is unfortunately not supported in the current version of the API Developer Portal. This will be considered in a future version, however, and ADP-1166 is now a Feature Request type (was previously filed as a Bug type). It was noted by Development that "the only workaround is to edit the HTML after the document has been generated and, unfortunately, such changes do not persist if the WADL is updated."
I apologize as I'm sure this was not the answer you were hoping for, but this is currently the state of ADP-1166. This will hopefully be included in a future version of the API Development Portal.
If you can (or want to) leave your customer name with me, I can add it to ADP-1166 to give it a bit more weight. Typically when reviewing new feature requests for future product versions, the Product Management team focuses on the areas where the most customers have requested items in addition to all the remaining feature requests which they review on a constant basis for future versions.
I hope this answers your question, but please let me know if there is anything further I can expand on for you and I will be happy to do so.
Sincerely,
Dustin Dauncey
