Actually, the values of the possible keys (the "using" attribute or
the sequence constructor of<xsl:key>) must all be atomic -- see:
http://www.w3.org/TR/2007/REC-xslt20-20070123/#element-key

"If the use attribute is present, its value is an expression

(b&)

The result of evaluating the sequence constructor is atomized."
This is why, using xs:anyAtomicType* is the precise return type of the
proposed function:
keys(keyname as xs:string) as xs:anyAtomicType*

Yes, I read that part but couldn't figure the type after the atomization. Now I see: the values must be atomic, and thus cannot be an user-defined type or untyped. The next part (in the spec) is easier to understand, I think: "16.3.2 The key Function key($key-name as xs:string, $key-value as xs:anyAtomicType*) as node()*" ==> $key-value as xs:anyAtomicType* ^^;

Thanks for you explanations, Dimitre and Ken.
