Does anyone know how to get XML from the Tuscany model objects thats
nicely formatted?
As a quick hack I came up with this but it seems like theres probably
something better and I'm not sure that
org.apache.xml.serialize.OutputFormat and
org.apache.xml.serialize.XMLSerializer are going to be there by default
in all runtimes:
I did something very similar in org.apache.tuscany.sca.itest.builder.TestUtils.
