Displaying locks on file externals

Hello!

One project here makes heavy use of file externals and locking,
building projects from a pool of binary objects
with this.

The question to solve is: who holds a lock where?

We use Tortoise SVN here, and it's developer told me, that this is a property of the svn library.

when I select a single file-external file with svn status -u, I see a lock held for this file.
If I use --xml, I see the lock owner.

when I run svn status -u --xml on the directory, there is no locking info shown.
Is this a bug? Can it be fixed easily?
It would help us here tremendously, if we could get a list, which of these (mainly file-external) files are locked (and by whom).

Mit freundlichen Grüßen
