Re:  current() in xsl:key
No, I donbt think thatbs right. XSLT 1.0 allows the use of current()
within any XPath expression, and says that it returns the same value as the
context item for the outermost containing expression. So itbs perfectly OK
to use it within xsl:key/@use.

The main change between 1.0 and 2.0 was that 1.0 banned the use of current()
in a pattern, whereas XSLT 2.0 allows it, and defines it to return the node
being matched against the pattern. This affects the match attribute of
xsl:key, but not the use attribute.
