>This DISCUSS had been raised about the URI Query Parameter method:
> 
>   * Section 2.3 URI Query Parameter
> 
>   This section effectively reserves a URI query parameter for the 
>    draft's use. This should not be done lightly, since this would be a 
>    precedent for the IETF encroaching upon a server's URIs (done 
>    previously in RFC5785, but in a much more limited fashion, as a 
>    tactic to prevent further, uncontrolled encroachment).
> 
>   Given that the draft already discourages the use of this mechanism, 
>    I'd recommend dropping it altogether. If the Working Group wishes it 
>    to remain, this issues should be vetted both through the APPS area 
>    and the W3C liaison.

>I wanted to let you know that the agreed-upon resolution to this issue is to 
>add the following text to the URI Query Parameter section:
> 
>    This method is included to document current use; its use is
>    NOT RECOMMENDED, both due to its security deficiencies (see
>    Security Considerations) and because it uses a reserved query
>    parameter name, which is counter to URI namespace best
>    practices [W3C TAG WebArch].

>The reference above is to http://www.w3.org/TR/webarch/.

>Thanks to Mark Nottingham, Stephen Farrell, Pete Resnick, and Dick Hardt for 
>helping us get to this resolution.
