[SMIL21 CR comment] mixing of normative and non normative

Hello www-smil,

Synchronized Multimedia Integration Language (SMIL 2.1)
W3C Candidate Recommendation 13 May 2005
http://www.w3.org/TR/2005/CR-SMIL2-20050513/

This document carefully notes for each section whether it is normative
or informative, which is good. I just noticed however:

http://www.w3.org/TR/SMIL2/smil-modules.html#smilModulesNSSMIL21ModuleProfileIdentifiers


2.4 Identifiers for SMIL 2.1 Modules and Language Profiles

This section is informative.

This section specifies the identifiers for the SMIL 2.1 namespace and
the SMIL 2.1 modules. Each SMIL host language conformant language
profile is requested to explicitly state the namespace URI that is to be
used to identify it. That namespace URI must comply with the
"Requirements on Identifiers for SMIL Host Language Conformant Language
Profiles", defined below.

a) If the section is informative, why is a conformance requirement (use of
'must') contained in it?

b) What does 'requested' mean? Is it that each host language must do it,
or should do it, or may do it? Please use one of the RFC 2119 defined
terms here.
