Re: [urn] NEW NAMESPACE REGISTRATION: KNX

[Peter Saint-Andre <[e-mail]>]

Hi Michael & all,

Although we typically like registrations to include a higher level of 
detail, I think we can approve this registration.

I do have one further question about the following text under Security 
and Privacy:

"The KNX Association may assign special meaning to certain characters
of the Namespace Specific String (NSS) in its specifications."

Because knxcloud.org is not responding to HTTP requests right now, I 
cannot download and check the specification for a description of this 
"special meaning"; however, what kind of security or privacy 
implications might there be?

Peter
