RE: [xsl] xslt key used with a predicate of an xpath expression

Yes, using current() would solve the first problem but not the second.

For the second problem, in XSLT 2.0 you can supply a third argument to key()
to indicate the document (or subtree) to be searched. In 1.0 you have to
change the context node by doing something like

<xsl:for-each select="$otherdoc">
  <xsl:value-of sleect="key(....)"/>
</xsl:for-each>
