By 'the English specification' I mean the normative parts of the spec, which
are formed from English sentences.
As apposed to normative parts of the spec which are formed from tables or text
eg: "2.2.1 {particles} is empty."

One should be able to put an annotation on  most elements within a schema, but
most importantly being able to add annotations to attributes uses
independently of attribute declarations. So 3.5.1 should also contain

If the annotation is captured for the other two, I don't see how, but it would
not be the first time I have misunderstood the spec!

I will restate my problem, I would like the "spec" to agree with the schema
schema in terms of where one can place a annotations.
The schema schema allows annotations on any <attribute> and <element>
I have attached a schema that I would like (need) to be valid.

You might ask why? do I want these annotations in these places, I am a member
of the JSR31 aka JAXB which is specifying how to bind XML schema into java, we
plan to use annotations to modify the default binding rules, there are
reasonable use cases for use where a user would want to place these
annotations on element and attributes with ref=.
