Update the content of a text section

You can add meta data to this call. In case of PROCEDURE sections you have to add the protocol's version ID and the values of its variables as meta data. Example:

{
    "contents": "[protocol HTML]"
    "meta": [
        {
            "name": "protVersionID",
            "val": "2344"
        },
        {
            "name": "version",
            "val": "1"
        },
        {
            "name": "protVar_7869",
            "val": "100"
        },
        {
            "name": "protVar_7871",
            "val": "0.3"
        }
    ]
}
