This may seem like a really obvious question, but I just wanted to make sure as I couldn't find any documentation on this particular attribute.
Within the site definitions
<site> there is an attribute called
<site name="service" enableTracking="true" virtualFolder="/sitecore/service" physicalFolder="/sitecore/service" />
I am wondering if this attribute is defaulted to true if it is not present?
Does it determine if an individual site has XDB tracking enabled / disabled? Or does it have another purpose?
