Does your statement answer the question on which has highest
priority in deriving the base, an inner Content-Location or
an outer Content-Base?

Does this mean that people are mapping directory structure to MIME
multiparts? For example, if you have a directory structure:


then this is sent via e-mail as

Content-Type: Multipart/mixed
Content-Disposition: attachment; filename=dir1
   Content-Type: text/plain
   Content-Disposition: attachment; filename=file1.1
   Content-Type: Multipart/mixed
   Content-Disposition: attachment; filename=dir1.2
      Content-Type: text/plain
      Content-Disposition: Attachment; filename=file1.2.1
   Content-Type: text/plain
   Content-Disposition: attachment; filename=file1.3
