Literals as Body

Hi,

I was wondering if

    {
        "@type": "oax:Comment",
        "oa:hasBody" : "No longer persian cats but golden retrivers are the
favourite pets in San Jose.",
        "oa:hasTarget": "_doc"
    }

is or should be allowed as a short form equivalent to

    {
        "@type": "oax:Comment",
        "oa:hasBody" : {
               "dc:format": "text/plain",
               "cnt:chars": "No longer persian cats but golden retrivers
are the favourite pets in San Jose."
        },
        "oa:hasTarget": "_doc"
    }

Cheers,
