Namespace prefixes make no difference, it's the namespace URI that counts.
So long as the URI is

http://www.w3.org/2001/XMLSchema

you can use any namespace prefix you like. As far as I can tell, "xs" and
"xsd" are equally popular. Perhaps "xsd" is used more in the Microsoft
community and "xs" in the rest of the world.

When I first came across this I thought that perhaps the convention was to
associate "xs" with the namespace quoted above, and "xsd" with
http://www.w3.org/2001/XMLSchema-datatypes. But this theory turned out to be
wrong. The XMLSchema-datatypes namespace is rarely used and is best avoided
because there are technical problems with it: it was supposed to be a
synonym of the XMLSchema namespace, but it turns out that it isn't an exact
synonym.
