Section 23.1 makes the definitive statement about when forward references are allowed, but it is true that expression properties also make the statement so yes the phrase should be added to the description of calendarLanguage.  It is also missing from choiceDispatchKey, and from setVariable.

Well, of course dfdl:outputValueCalc can also have forward reference. I meant all properties except this.

Every property that can be an expression needs to stipulate "The expression must not contain forward references to elements which have not yet been processed."

There are only two exceptions which are for the message of asserts/discriminators.

This phrase is missing for calendarLanguage.
