When the argument to document() is a node, then the string value of a node
is taken as a relative URI and is resolved against the base URI of that node
(that is, it's relative to the source document). When the argument is a
string, then the string is taken as a relative URI and is resolved relative
to the stylesheet.

There's a very rarely used feature of the document() function that helps you
here: you can supply a second argument which is the node whose base URI is
used for resolution. So try:

document(concat(., '.xml'), .)
