OK. Having switched VoiceOver to English, I can verify. My very bad.

More attention than conclusion, IMO.

To a VoiceOver user, what comes across as most 'clean'? The title 
attribute solution currently in the text, or one or both of your 
proposed replacement examples? 

If L = 'Part number', H = the instruction text and E = cue to edit the 
text field, then the VoiceOver experiences can be summarized like so:˙

  Current spec: LHLE
Your example 1: LLHEH
Your example 2: LLEH

All the above are automatically read to the user. The difference 
between your two examples w.r.t. what is automatically read to the user 
before the edit text cue, is interesting.

Regarding help tag upon request: In the current spec example, the title 
attribute is used as help tag text. In your first example, there is no 
specific 'help tag', as VO sees it - everything is read if the user 
asks for help tag. In your second example, the aria-describedby text is 
used as help tag.

To me, the behavior that the current spec example generates, seems more 
straight forward. But of course, I don't have not observed users using 
a form. Neither do I know how other ATs present the examples. 

But, at least seen from a VoiceOver perspective, there are some 
drawbacks to the solutions you propose. Also, I’m sure many authors 
would like to have invisible help tags/descriptions.
