XQuery 1.0: An XML Query Language
W3C Working Draft 12 November 2003
3.7 Constructors,
A.1 EBNF
I think it would be an improvement if you changed
    [80] Constructor        ::= DirElemConstructor
                                | ComputedConstructor
                                | XmlComment
                                | XmlPI
                                | CdataSection 
to
    [80] Constructor        ::= DirectConstructor | ComputedConstructor
    [new] DirectConstructor ::= DirElemConstructor
                                | XmlComment
                                | XmlPI
                                | CdataSection 
This would better reflect the division between computed and direct
constructors. Incidentally, it would also mean that you could change:
    [109]   ElementContent  ::= ElementContentChar
                                | "{{"
                                | "}}"
                                | DirElemConstructor
                                | EnclosedExpr
                                | CdataSection
                                | CharRef
                                | PredefinedEntityRef
                                | XmlComment
                                | XmlPI
to just:
    [109]   ElementContent  ::= DirectConstructor
                                | ElementContentChar
                                | "{{"
                                | "}}"
                                | CharRef
                                | PredefinedEntityRef
                                | EnclosedExpr
------------------------------------------------------------------------
Moreover, if you introduced
    [new]  CommonContent  ::= PredefinedEntityRef
                              | CharRef
                              | "{{"
                              | "}}"
                              | EnclosedExpr
then you could eliminate a bunch of repetition in [109,112,113]:
    [109]  ElementContent       ::= DirectConstructor
                                    | ElementContentChar
                                    | CommonContent
    [112]  QuotAttrValueContent ::= QuotAttContentChar | CommonContent
    [113]  AposAttrValueContent ::= AposAttContentChar | CommonContent
