4.2 Path Expressions

Introduction
[68 (XQuery)] RelativePathExpr ::= StepExpr (("/" | "//") StepExpr)*
    The Normalization rules (4 and 5) assume a right-recursive production,
    something like:
        ... ::= StepExpr | StepExpr ("/"|"//") RelativePathExpr

Norm / rule 1
    The RHS has to be enclosed in []_Expr because 'treat as' is not in
    the Core language.

Norm / rule 3
[[ "//" RelativePathExpr ]]_Expr == ...
    Delete the quotes.

Norm / rule 3
"treat as document-node"
    Append "()" to "document-node".
