If a webservice offers responses in XML, YAML, and JSON formats, which is the best choice to consume? I'd normally choose XML and use XML::LibXML to parse. But I may eventually upload to CPAN, and would like to make it easier on users and avoid unecessary prereqs.

I took a look at many of the WebService::* modules and they mostly consume XML, and as expected, there's no consensus on an XML parser. There was one module, WebService::Eventful, which strangley enough, consumed all three formats: XML, YAML, and JSON.

I'm leaning towards YAML now, since some of the internal perl stuff is using it (e.g. META.yml), but am open to opinions.
