Yes, just understand that the key declaration doesn't name any document,
does not refer to any document so just declare as you would declare it
for a primary document.

Then (in XSLT 2 and later) pass the secondary document you want to use a
key on in the key function call as the third argument e.g.

B  key('key-name', key-expression, $doc1)

or use e.g.

B  $doc1 ! key('key-name', key-expression)
