1.1 A Note on Notation and Usage

Where EMPHASIZED, the key words MUST, MUST NOT, REQUIRED, SHOULD, SHOULD NOT, MAY in this document are to be interpreted as described in [keywords] .

Note that many of the nonterminals in the productions in this specification are defined not here but in the XML specification [XML] . When nonterminals defined here have the same names as nonterminals defined in the XML specification, the productions here in all cases match a subset of the strings matched by the corresponding ones there.

In this document's productions, the NSC is a "Namespace Constraint", one of the rules that documents conforming to this specification MUST follow.
