how is Detail.xmlString supposed to work

[janwiebe-jump]

I would like to add special data to my CotEvent.
I do this by using the xmlString property at Detail.

new Detail()
{
     xmlDetail = """"<__special count="3" />""""
};

I assume it would serialize like this: (but I am not sure, I don't get the TAK / protobuf specs fully)

...
<detail>
        <__special count="3" />
    </detail>
...

However, it looks like it is serialized like this:

<detail><xmlDetail>&lt;__special count="3" /&gt;</xmlDetail></detail>
