--0000000000007f54ba06303ac947 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable No worries. The code starting the XML Attribute support for XML Stream, as discussed in this email thread, went out with Axis2 2.0.0 release this past Monday. Axis2 is now jakarta based, so you will need the latest Tomcat or Wildfly to run it. If you need any help finishing this support, let me know. What needs to happen now is someone with this use case and motivation to debug it until it works. I don't have this use case myself and am busy on other things at the moment, but I am highly motivated on improving our overall JSON support and will do what I can to see this feature get implemented.
