Public procedure registerFunction(const name: string; minArgCount, maxArgCount: integer; func: TXQBasicFunction; const typeChecking: array of string); overload;

Registers a function that does not depend on the context. TypeChecking contains a list of standard XQuery function declarations (without the function name) for strict type checking.

Public procedure registerFunction(const name: string; func: TXQBasicFunction; const typeChecking: array of string);

Registers a function from an XQuery body TypeChecking must a standard XQuery function declarations (without the function name but WITH the variable names) (it uses a simplified parser, so only space whitespace is allowed)

Registers a binary operator TypeChecking contains a list of standard XQuery function declarations (with or without the function name) for strict type checking.
