My thoughts on a multipart/related format for forms are to start with
an SGML based encoding for most fields and to use additional parts
as needed for data which doesn't fit neatly into the SGML scheme, e.g.
audio, pen input (as JOT), and file data. This way you normally just
see one part.
The next step is to define the SGML DTD for form contents and to
specify the naming scheme for referencing data in other parts.
The SGML ID notation springs to mind here.
