I strongly suggest not to invent urn's like this, even if this is just 
an example. This will be archived on the web and can always be found later.

We do not know at all whether IEEE, ANSI or the ITU have URN namespaces 
like this. Or even if they do, that they want to identify their 
technologies like this.

In absence of a better identifier I suggest using a URL to the standard. 
Or the group that wrote the standard if none is available.
I agree that this is incredibly annoying, and that we'll probably have 
to maintain a list with identifiers for technologies. But we can't just 
make stuff up while referring to other standards organisations.

So:
802.3ab: http://grouper.ieee.org/groups/802/3/ab/index.html
eia-568-a: http://standardsdocuments.tiaonline.org/tia-eia-568.htm
802.3-2008: http://standards.ieee.org/getieee802/802.3.html
etc.
