I'm not sure I correctly understand the first half of your question, but you 
can either query for the existence of a given document:

empty(document('/db/test/test.xml'))

will return true if the document does not exist. Or you can directly ask for 
some root element:

empty(/test)

Cocoon path tokens are not yet passed to the XQuery engine, but I think I can 
add that easily.
