VS: SIPit21: BNF future-proofing problem?

Hi,
 
No matter how we'll fix this, I guess it would be a valid
essential correction?
 
Regards,
 
Christer

   This strikes me as a problem in theory and not in
practice. AFAICT, the
   only characters you can't use are ascii 0x00-0x19 (0x20
is space and is
   possible through the LWS construct as Christer pointed
out). Is there a
   practical use case for any of these? They are:

HT (horizontal tab) should be included, but that's also in
LWS.  As
for the remaining characters, I don't think that anyone has
ever
*intended* that they be used in SIP headers, and their
inclusion in
quoted-pair was a typographical error.

Correction, yes. Essential? Hardly.

This is another question around essential corrections. I
think they not 
only need to clearly represent a bug or a fix, but need to
be one that 
is important enough to merit documenting. Just like
software, sometimes 
you don't ever bother fixing those sev 5s. Ever.
