Not in any useful way. The key() function can only be used to find nodes in
the current document.

You're confusing the key definition (<xsl:key>) which is a top-level
element, and the key() function, which is used to retrieve nodes using the
key.

You could generate an XML document that acts as an index, and reference this
document in a subsequent run using the document() function. But you can't
save the key index per se.
