When Displaying the XML Representation of a Task following the README for tasks-rs I get this XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<collection>
    <task id="1" ownerName="quickstartUser">
        <title>task1</title>
    </task>
</collection>

README says:
Using either of the above GET methods, you should see the following XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<task id="1" ownerName="quickstartUser">
    <title>task1</title>
</task>
