[Bug 29355] Modernize sequence filtering

https://www.w3.org/Bugs/Public/show_bug.cgi?id=29355

--- Comment #9 from Michael Kay <mike@saxonica.com> ---
But $sequence[@x, @y, @z] makes perfect sense, it selects those items in the
sequence that have at least one of the attributes x, y, and z.

I think overloading a[b] to do both filtering and positional selection was a
bad idea, but given that it was done, it's hard to identify changes that would
make things better without breaking compatibility.
