           Summary: [UPD] Sections 2.4.*: Target should allow empty sequence
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: critical
          Priority: P2

Update target should allow empty sequence to make this usable in a static
typing context. Semantics where target is empty is a no-op.

Currently an expression such as (/a/b)[1] as a target will most likely fail
because it is statically typed as b?.
