Take a look at the results of Use Case "NS", query 2:

http://www.w3.org/TR/xquery-use-cases/#ns-queries-results-q2

        <title xmlns="http://www.example.org/music/records" 
               xmlns:anyzone="http://www.example.com/auctioneers#anyzone" 
                   xmlns:eachbay="http://www.example.com/auctioneers#eachbay" 
                   xmlns:ma="http://www.example.com/AuctionWatch"
               xmlns:xlink="http://www.w3.org/1999/xlink" 
                   xmlns:yabadoo="http://www.example.com/auctioneers#yabadoo">In a Silent Way</title>

Does it bother you that a simple string-valued element carries so much 
baggage? It's overhead for the systems involved, and it makes the 
results harder to read if serialized according to our serialization 
rules. Imagine that the same data gets queried repeatedly, stuck in SOAP 
messages, and passed on. The namespace declarations from each SOAP 
envelope keep accumulating over time.

Does this help?
