Hi,
the root node indeed allows same name sibling child nodes. I suggest
you move everything one level down. something like:
root
root-folder
folder1
sub-folder1
content1
content2
sub-folder2
content1
content2
folder2
........
where root-folder is nt:folder and is created initially by the system.
regards
marcel
