bah humbug, you can't do  /h:html/h:head/h:meta in pure xpath either 
since you rely on a host language to bind the xhtml namepsace to the 
prefix h. The fact is that Xpath2 allows the host language to specify
the default namespace for elements in queries, and xquery chose to 
specify that was the same as the default namespace for element 
construction, which was a bad mistake.
