Sequence context on variable/option

/ Innovimax SARL <> was heard to say:
| I think making it an error would allow us to allow it later...but I would be
| pleased to allow it right now when XPath 2.0 is selected

There is a streaming/performance impact: an implementation will have
to provide the whole sequence to each variable/option.

| On slight thing, how do make the difference between an empty document and an
| empty sequence ?

You mean for the XPath 1.0 case? I think if we allow sequences we
should make XPath 1.0 implementations simply take the first document
on the sequence.
