It seems that there is a mixup in the backend code for including an 
attachment.

For example, when I use:

\setupinteraction[state=start]

\starttext
The current file is \attachment[tag][file=\jobname.tex, name=test.tex, 
title={Whatever}]
\stoptext

I was expecting that the current file will be attached as "test.tex" and 
title "Whatever. However, the title of the attached file is "tag".

See the attached screenshot from Adobe Reader.

It seems that in the back end, tag is written to the PDF file where title 
should have been written.

we can do this (line 308 of lpdf-wid)

     if author == "" and title ~= "" then
         author = title
         title  = filename or ""
     end

but you can also add an author field to the specification as what shows 
up in the pdf is partly the side effect of fallbacks for missing fields

(and ... it's one of these pdf features that is unreliable anyway as 
it's viewer dependent .. read: specs before implementations and then 
acrobat behavior defining what will happen; the whole 'associate 
rendering with some annotation mechanism is fragile as depending on the 
version of acrobat it works this or that way, probably because no 
application uses plugged-in rendering, it's the same with form fields 
... a depressing mess)
