Yes it can. Of course, you first need an implementation that supports
a URI scheme that can scan directories. Arguably, file is legitimate
for this, as browsers usually give you a directory listing if you
supply a file URI that ends with a directory name.

What Gestalt does it return a sequence of documents each containing a
single element, which has various information about that directory
entry. You could then call unparsed-text on the document-uri for that
particular entry.

Note that that URI is not a legitimate file URI (they may not take
query parameters). Saxon is not compliant in this respect (but even if
it were, there is no particular reason that this should work - the
collection() function is very loosely define.
