There's some basic misunderstanding here about what a key is. Think of <xsl:key> as being like "create index" in SQL: it defines an index for all the "match"ed nodes in the document, that allows them to be retrieved using the value of the "use" property. The contents of the index are fixed when the source document is loaded, it doesn't make sense to change them depending on the contents of a variable.
