Implementation
direxists is implemented as an xsh script which simply calls xdmp:document-properties. The source of the script is
# return true if diretory exists else return false
_opts=$<(xgetopts -a -p "c=connect:" -ps -- "$@")
shift $?
:query $_opts -b -q <{{
declare variable $uri external ;
exists(xdmp:document-properties($uri)//prop:directory)
