>>[R94a] Empty elements MUST not be declared

This is more a comment on the editorial.  I kind of get 
what is said here, but what does it mean by "declared"?  
In schema (e.g. an element that references a complexType 
that has no content but only attributes), or in instances 
(that may or may  not have been described by (c))? 

May be clarifying it a little further would be helpful.

Again, just picking on the editorial, "MUST not appear" 
means must not appear in schema or instance or both?
I'm not really asking for the answer so much as to ask
for the rule to be described clearer.


Will it be useful to have a "tag" on all rules (main and
sub-parts), that indicate the scope of applicability 
with regards to "schema", "instance" or "schema & instance"?

For e.g., 

[R94a] (Schema, Instance) Empty elements MUST not be declared

[R94b] (Instance) The XSD built in nillable attribute MUST NOT 
                  be used for any UBL declared element.

[R94c] (Instance) An element MUST not appear without content in 
                  the document instance. [remember to add in 
                  narative that there is an issue with string
                  length of 0.]
