Hi Peter

Something like the example below, but I suspect that this might not make it
> a real geo:Point?

barely. The old maths teacher in me frowns at points having a radius :)


>   <geo:Point>
>     <geo:lat>55.701</geo:lat>
>     <geo:long>12.552</geo:long>
>     <dwc:radius>10</dwc:radius>
>   </geo:Point>
>

What about something as the following, since the radius is not really a
property of the point ...

<geo:Area>
    <geo:center>
        <geo:Point>
            <geo:lat>55.701</geo:lat>
            <geo:long>12.552</geo:long>
        </geo:Point>
    </geo:center>
    <dwc:radius>10</dwc:radius>
</geo:Area>

namespaces ad libitum of course

Cheers

Bernard
