No.

Attributes live in the global namespace by default; they do *not* inherit
the default namespace, unlike elements.  Therefore, your first example above
defines the result you show, and the second defines:

<{ns:ns:ns}elem {}attr="smth" />

The only way to get an element in a namespace is to put it there; an
attribute without a prefix is always in the global (unnamed) namespace.

This usually confuses people, because it isn't the way that elements behave. 
It is, however, what the namespaces specification defines.
