SWITCHYARD-628 added a new configuration element ("securityAction") to the soap binding, and should be reflected in the tooling:

<binding.soap>
<!-- ... -->
<securityAction>UsernameToken</securityAction>
</binding.soap>

In the tooling, for 0.8, just make it a free-form text field. This could change in the future (in fact, it will). But for now the user can put whatever they want in it, for example:

<securityAction>Signature Encrypt</securityAction>

There will be a wiki article about this in the near future.

The new element shows up in the xsd schema here: http://goo.gl/ZUtb6

Note that there are also new <inInterceptors> and <outInterceptors> elements as well. These do not have to be supported in the tooling for 0.8.
