<selector xpath="."/> doesn't work

Hello,
I am using <key> and <keyref> in my XML Schema.

When I declare the <key> element globally ('AdminUnitKey_Global'), the key's
are set appropriatly.

When I want to declare the <key> element locally ('AdminUnitKey_Local'; by
using the expression <selector xpath="."/ under the <AdminUnit> element) the
key is not set and the schema does not validate because the <keyref> fails to
refer to some key.

I thought that xpath="." refers to the current element where the xpath
expression is set? Why doesn't that work with <key>?

Thanks, Markus
