For me Infinity is more or less equal to not defined. Therefore I think
it is a nice way to disable certain options without having an additional
flag. Maybe NaN would be also a way to express it.

But I am not sure if we can set the values from ruby or orogen. If not I
would drop the idea.

--> property 'val1','double','NaN' would be nice
