    docs: retrospectively add XS_DIRECTORY_PART to the xenstore protocol...
    
    ... specification.
    
    This was added by commit 0ca64ed8 "xenstore: add support for reading
    directory with many children" but not added to the specification at that
    point. A version of xenstored supporting the command was first released
    in Xen 4.9.
