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:

dir1
   file1.1
   dir1.2
      file1.2.1
   file1.3

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
