You might as well just say match="Value", unless you really do have
Value elements which are *not* children of a LookupTable and you want
to ignore them.

Not quite. This will either return an empty string or the string
value of the *whole* LookupTable.xml document, according to whether
there are any nodes in the document matching $currentKey.
You are executing the key() function in the right context, but
unfortunately there isn't a way of getting at the value: it is being
cast to a boolean which is then used to filter the node set $lookup,
which contains a single node which is the root node of the
LookupTable.xml document.
See Wendell's message for the right approach, using xsl:for-each. Or
use XPath 2.0, where there is a pure XPath syntax for changing
context.
