RE: [xdi] reserved words disallowed for e-names

["Loren West" <loren.west@epok.net>]

My resistance may come down to a matter of definition.

I've always considered e-names and e-numbers as fancy
words for non-persistent and persistent XRIs (respectively)
that can be used anywhere in the XDI web.

One important place they're used is in the = and @
namespaces, and I've seen those e-names / e-numbers
referred to as "global e-names / e-numbers".

If, however, I've gotten my definition of e-name/e-number
wrong, and they really mean "the things registered under
the = and @ namespaces", then the usage of the term
"global" is redundant.

If e-names really are defined the way I thought, then
I have a problem with reserved words in the e-name
specification.  They should be in the "global e-name"
specification.

I understand the reason behind restricting single and double 
letter global e-names, but aside from "Example", I don't
see the reason to restrict any of those proposed e-names in 
the global e-name specification.

My thinking about why some names ought to be reserved regards 
documentation, similar to RFC2606 that reserves e.g. example.com.  Being 
able to write documentation that includes examples like 
'@community/member' and '=user' without these names referring to actual 
entities is, IMO, valuable.

I agree that if any names are reserved at all, it would be most 
important that they are reserved at the root, e.g., the = and @ name spaces.

Note that I also pose the question of disallowing one and two-character 
e-names, and e-names with any xri-reserved character in them (though the 
ABNF allows (e.g) this subset:  ;!*@&=+$,
