Adobe SiteCatalyst - What does D mean in prop6=D=": "+pageName

Question

I see this often in Adobe SiteCatalyst (Reports and Analytics / Omniture / they've changed the name so many times)

prop6=D=": "+pageName

In the above s_code what does the 'D' do?

(It's difficult to find anything about the above behavior in a standard search)

Answer 1

It's a dynamic variable. Here is some documentation from Adobe:
