Re: Is the fixed-attribute on length-facet useless?

Okay, to go go a step further, this should be regarded as an error
in the spec?

In my opinion, it causes misunderstandings, that are not necessary.
May sound a bit harsh, but I would favour dropping it ;-).

Yes, Jeni, vitally important was a bit exaggerated. Sorry for that.
Thinking about an use-case I get the notion of a password-type (maybe
with some sort of special feature ) in a schema, that serves as a 
base for derived types. A fixed-attribute on minLength would make sense, 
in order to prevent a user to derive a type by restriction, that would
allow a password with less than the minLength value.
Any use-case I can possibly think of goes in the direction, how to protect
a base type....
