you're right, i'm really out of the scope of WXS, except for primitive types

   So, you are safe by

what people would think if i use my:element ? xml:element is more 
"natural" and anybody may understand what i'm talking about ; if people 
encounter my:element, they could think that it has something special 
regarding the usual XML element...

so, i decide anyway to keep my first idea, and warn that xml:element and 
others are understandable only in the scope of the spec i'm working on

i'm just looking of a way of naming types with a qname ; and it is not 
as simply as it seems
