I'm confused !
If you turn directory creation to manual.
Suppose you create a XML file with URL
/foo/bar/spam.xml
My 'understanding' (from reading the ML docs) is that there is no directory
"/foo/bar/"
Since no directories were created, none exist.
Is this just terminology ? or is there something else under the hood I'm
missing.
To me this implies that URI's need not have "directories" associated with them.
Is this wrong ?

David, that approach works as long as your directory has a corresponding
directory fragment (either with directory-creation=automatic or with
manually-created directories). But it's also possible - and fairly
common - to use xdmp:directory() without having any directory fragments
(directory-creation=manual). Most large database applications set
directory-creation=manual for efficiency reasons. So any general-purpose
code should be written to work for both cases.
You might think of these as explicit vs implicit directories. A webdav
client will only see explicit directories: it needs the directory
fragment for locking purposes. But any database query can make use of
implicit directories.
For most purposes I would use lock-free code to check for a directory uri:
xdmp:exists(xdmp:directory($uri, 'infinity'))
