No, there're no utilities (in CXF) for wrapping String values into
corresponding name:value JSON sequences or xml elements.
What sort of wrapper names would be acceptable for Strings ?
is it 'string' ?
so List<String> can be then be serialized like :
<strings>
<string>foo</string>
<string>foo</string>
<strings>
or
{{"string":"foo"},{"string":"bar"}}
?
cheers, Sergey
