Re: [Bug 5462] Can sml:nilref="true" be specified on a non-SML reference?

Michael typed in IRC some text related to this topic. It may be worthwhile 
to take a look there.

I would want to avoid "MUST ignore", because it's not ignored in, e.g., 
schema validation, rule checking, etc. Maybe something like "has no 
effect" is more appropriate. ("No effect" should already be a consequence 
from it's normative definition/semantics, so no need to use "MUST".)

Section 4.2.5 now reads (last sentence is new):

4.2.5 Null SML References

An null SML reference is an explicit declaration of intent by the document
author that the SML reference itself does not exist, and a processing 
directive
(not a hint) to processors not to attempt to recognize any reference 
schemes in
it. If an SML reference is recognized as null, then processors MUST NOT 
attempt
to resolve it.

Processors MUST ignore an sml:nilref attribute when present on an element 
that
is not an SML Reference [4.1.1 SML Reference], in which case the consumer 
MAY
issue a warning to its invoker.
