Subject: [Speechsc] Min-Verification-Score: clarification needed

Hi,

comparing new verification-header Min-Verification-Score description with Speechsc Forum discussion (see http://www1.ietf.org/mail-archive/web/speechsc/current/msg01409.html and http://www1.ietf.org/mail-archive/web/speechsc/current/msg01414.html).

We think that header description contains some errors (see below)

---
1) old name in Section 11.4

In Section "11.4  Verification Header Fields" there is:
"/  confidence-threshold"
instead of
"/  min-verification-score"

---
2) old names in Section 11.4.6

The section "11.4.6  Min-Verification-Score" reads:
"The confidence-threshold header, when used ..."

It should be:
"The Min-Verification-Score header, when used ..."

---
3) Inconsistent values: Range -1:1

The current value of 0.0-1.0 seems to be not consistent
with the resolution in:
http://www1.ietf.org/mail-archive/web/speechsc/current/msg01414.html
which states:
I will change this and the newly-renamed min-verification-score header to -1:1 range unless I hear objection with persuasive rationale.
<<<
and the ABNF definition
>> min-verification-score  = "Min-Verification-Score" ":" [-] Float-value CRLF

---
4) Inconsistent description

Also the second part of the sentence:
  "This is a float value between 0.0-1.0 indicating the verification
   engine's confidence in the recognition."
seems to be not aligned with the new definition that reads:
  "... determines the minumum verification score for which a
   verification decision of "accepted" may be declared by the server."

We suggest either to remove: "indicating the verification
   engine's confidence in the recognition."
or to re-phrase it.
