Internet-Draft              ni URI Parameters               October 2011

1.  Introduction

   The ni URI scheme [nischeme] supports extensibility in terms of the
   algorithm used to derive a value (normally, but not always a strong
   digest algorithm) and via support for a query-string thay can contain
   a list of key=value pairs.  This document defines some uses for both
   of these extensibility points and creates IANA registries that can be
   used to register additional algorithms and key strings for use in the
   query part of an ni name.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   [[Comments are included in double-square brackets, like this.]]

   [[Note that the features here are less mature than the specification
   in the [nischeme] document.  The intent is to develop these as
   required for the various use-cases as we go.  If something from here
   appears to be as widely useful as the core ni scheme, then the
   authors are willing to move features from this document to the core
   document.  We are also happy to incoroporate features to handle
