Uhm. I realize that is rather vague, now that you mention it. I meant  
FLWR/SELECT statements.

We're not dealing with formal semantics just yet, because we want to  
get community feedback on what we are trying to do first, before  
trying to specify it fully. The formal semantics will be done later,  
once we have agreement on the form of the language. (And probably they  
will look rather like what is already in the draft.)

Tuple operations: this was deliberately omitted from the path language  
proposal. I've added a slide making this clear.

Set operators: as the slides say, this will be provided in SELECT/FLWR  
statements, but not as part of the path expressions.

I'm not sure I understand this question. What do you mean?

Sounds great. Certainly worth a try.
