local-name of attribute values

Hello everybody,

I have an attribute base="ns:type" and want to get the local name of 
the value, i.e. "type" in this case. Obviously this is the substring 
after ':'. If there is base="type" then it is the whole string.

A single XPath expression for this could be

concat(substring(substring-after(@base,':'), 
                 1 div contains(@base,':')),
       substring(@base, 
                 1 div not(contains(@base,':'))))

(see http://www.dpawson.co.uk/xsl/sect2/N6461.html#d58e628 for an
explanation)

Does anybody know a shorter XPath 1.0 solution?
(I need this as an expression for xsl:key)

Cheers,
Oliver
