Static typing is not the same as strong typing. It's hard to have a
discussion if people can't get figure out exactly what they are talking
about. As for static vs. dynamic typing, a number of folks I know who
work with XML seem to like the capabilities of strongly typed dynamic
languages just as much or more than strongly typed static languages. 

In the context of XQuery, which is what this thread was originally about
users can have both as Micheal Rys pointed out the working group has
taken care to design the language in that way. I can as easily write 

  
 define function summary($teacher as element()*) as xs:integer {
count($teacher/student) } 

as I can 


  import schema namespace myns ="http://www.example.org" 
            at "http://www.example.org/school.xsd"

  define function summary($teacher as element(myns:teacher)*) as
xs:integer { count($teacher/myns:student) }
