I think having a binary rule for the sequence construction is probably better.

The way sequences of values behave is described in [XQuery 3.3 Sequence
Expressions] and [Data Model 2.5 Sequences].

Those rules are recalled in [Formal Semantics 2.3.1 Formal values] (second
paragraph from the end of the section). We may want to add a pointer to the data
model there for clarification.

We may want to formalize those rules on sequences by adding something along the
lines that you propose. I believe the following would be a bit cleaner, and more
complete as well. But I am not completely convinced this is necessary.


  ---------------
  (Value) = Value


  -------------------
  (), Value2 = Value2


  -------------------
  Value1, () = Value1
