Definition of the grammar syntax

Hi,

 

I was looking at the production rules in the XML specification
(http://www.w3.org/TR/xml11). I wanted to fully understand the grammar used,
so reviewed the opening sections of the document to look for a reference to
the syntax / semantics that the grammar definitions are based on. For one
who has limited familiarity with grammars, I do not fully understand, for
example, the following:

 

Production rule [1] document - see
https://www.w3.org/TR/2004/REC-xml11-20040204/#NT-document

 

Production rule [10] AttValue - see
https://www.w3.org/TR/2004/REC-xml11-20040204/#NT-AttValue

 

Nowhere in clause 1 could I find the normative reference to the grammar for
these rules. Fortunately, I happened to scroll down to look at the
references at the bottom of the document, and chanced upon clause 6
Notation. Please can a forward reference to this clause be added to clause
1.2 Terminology, so that readers are immediately aware where to locate this
information. This would then align with  the other terminological details,
such as, for example, the use of verbal forms and the reference to IETF RFC
2119.

 

Many thanks in advance,
