[DAS] pinging source

[Jonathan Warren]

My vote at the moment would be to have the source element.

On a side note: My vote would also be to not have nice human readable  
stylesheets at all ;) Though I accept I may be a lone voice on this  
one. Mainly because I want DAS to be as powerful as possible while  
being easy for new users to get into ( some people who have provided  
das sources for years have not known they could just right click and  
select "show source" to get the xml and see that their new elements  
are shown in the xml but are not in the stylesheet!!). It justs adds a  
layer of complexity and confusion for little gain in my opinion. The  
alternative would be to have raw xml as default and stylesheet as an  
option - presumably that could be done? Maybe I missed the whole point  
about putting them in? Surely people use das in a browser for  
discovery and testing not actually viewing data on a day to day basis?
