[MarkLogic Dev General] element queries

[Shannon Scott Shiflett]

Mike, I was referring to the example given in the function  
documentation for cts:element-attribute-value-query(), but you are  
right, that is not exactly what I was looking for.  The solution you  
provide is indeed good enough, thanks.  I hope your enhancement  
request to have cts:element-query include its own attributes is  
accepted.
